# Search for narrow resonances in the -tagged dijet mass spectrum in proton-
proton collisions at $\sqrt{s}=8\TeV$

###### Abstract

A search for narrow resonances decaying to bottom quark-antiquark pairs is
presented, using a data sample of proton-proton collisions at $\sqrt{s}=8\TeV$
corresponding to an integrated luminosity of 19.7. The search is extended to
masses lower than those reached in typical searches for resonances decaying
into jet pairs at the LHC, by taking advantage of triggers that identify jets
originating from bottom quarks. No significant excess of events is observed
above the background predictions. Limits are set on the product of cross
section and branching fraction to bottom quarks for spin 0, 1, and 2
resonances in the mass range of 325–1200. These results improve on the limits
for resonances decaying into jet pairs in the 325–500mass range.

Searches for new particles decaying to pairs of jets are pursued vigorously at
hadron colliders, repeated at every new energy with ever increasing
sensitivity in the quest for physics beyond the standard model (SM). Such
“dijet” final states have been explored in proton-antiproton collisions by the
UA1 [1] and UA2 [2, 3] Collaborations at the CERN S$\Pp\Pap$S, and at
$\sqrt{s}=1.8$ and 1.96by the CDF [4, 5, 6, 7, 8, 9] and D0 [10, 11, 12]
Collaborations at the Fermilab Tevatron, as well as in proton-proton
($\Pp\Pp$) collisions at $\sqrt{s}=7$, 8, and 13by the ATLAS [13, 14, 15, 16,
17, 18, 19, 20, 21, 22] and CMS [23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33,
34, 35] Collaborations at the CERN LHC.

The LHC dijet searches currently explore both the high-mass end of the
spectrum, not previously accessible at lower-energy machines, and the low-mass
range, aiming to gain sensitivity to much smaller couplings than those probed
by earlier experiments. The latter searches are much more difficult because of
the very large backgrounds, which result in overwhelming event rates that are
beyond the typical trigger bandwidth of the ATLAS and CMS experiments. To
address this challenge, several novel search strategies have been considered.

Recently, the CMS Collaboration introduced the idea of a trigger-level
analysis, which profits from the fact that the trigger acceptance rate can be
increased significantly if the size of the event is kept small. Thus, it is
possible to collect events at an increased rate using a specialized trigger-
level data output, which keeps only minimal information about the event. The
trigger-level analysis, also referred to as a “scouting analysis” in CMS,
enabled the mass reach of LHC dijet searches to be extended down to masses as
low as 500 [33].

Another way of lowering the mass reach of dijet searches is to use an initial-
state radiation (ISR) jet or photon to trigger on an event and analyze the
dijet system recoiling against the ISR object. Given that the ISR triggers
typically require a rather high threshold for the transverse momentum () of
the ISR object, for sufficiently light resonances the two jets from their
decays may be merged and reconstructed as a single large-radius jet. The mass
of such a jet, determined using the so-called jet substructure techniques, can
then be used to search for new light resonances. Searches of this kind,
recently pioneered by CMS [36, 37], for the first time can reach resonance
masses as low as 50, , well below the lowest previously probed mass of 140,
achieved by the UA2 analyses [2, 3]. A similar analysis has been very recently
carried out also by ATLAS [38].

Yet another strategy of extending the reach to lower masses, pursued in this
Letter, is to look for resonances decaying into jets originating from the
fragmentation of quarks. The dominant QCD background in the final states is
significantly reduced compared to that in generic dijet final states, allowing
for lower trigger thresholds and increased search sensitivity, particularly
for resonances decaying preferentially into third-generation particles.

Beyond the SM theories predict a variety of such resonances, , resonances in
top-assisted technicolor models [39], Kaluza–Klein excitations of the graviton
in the Randall–Sundrum (RS) models [40, 41] with SM particles allowed to
propagate in the bulk space [42], or additional scalar or pseudoscalar
resonances with Yukawa-like couplings to quarks, as expected in the general
class of two Higgs doublet models [43] or models with spin-0 dark matter
mediators [44, 45]. However, even for resonances not preferentially decaying
to final states, the sensitivity of a quark dijet search may rival that of the
generic searches because of the drastically reduced backgrounds. Searches for
new, massive resonances decaying to final states have been explored for the
first time by the CMS [31] and ATLAS [21] Collaborations. Yet, these searches
only relied on the standard jet triggers used in the generic dijet searches,
and therefore the minimum mass probed was as high as 1100 (ATLAS) or 1200
(CMS) . It is of particular importance to extend the mass reach of these
searches below 1000, for which the existing limits are still rather weak.
Moreover, the channel is particularly important for resonances with enhanced
couplings to third-generation particles and with masses below the threshold of
about 350.

The above three strategies are complementary to each other, as they vary in
sensitivity to different production and decay mechanisms of new, light
resonances. This Letter presents the first search for resonances with masses
as low as 325, , below the threshold, using dedicated triggers requiring the
presence of quark jets. The results improve upon the sensitivity of existing
generic dijet searches to models predicting such resonances. The results are
interpreted in the context of a spin-0 resonance, spin-1 boson, and spin-2 RS
graviton, whose intrinsic widths are small compared to the experimental
resolution.

The central feature of the CMS apparatus is a superconducting solenoid of 6m
internal diameter, providing a magnetic field of 3.8T. Within the solenoid
volume are a silicon pixel and strip tracker, a lead tungstate crystal
electromagnetic calorimeter (ECAL), and a brass and scintillator hadron
calorimeter (HCAL), each composed of a barrel and two endcap sections. Forward
calorimeters extend the pseudorapidity ($\eta$) coverage provided by the
barrel and endcap detectors. Muons are detected in gas-ionization chambers
embedded in the steel flux-return yoke outside the solenoid. Events of
interest are selected using a two-tiered trigger system [46]. The first level
(L1), composed of custom hardware processors, uses information from the
calorimeters and muon detectors to select events at a rate of around 100kHz
within a time interval of less than 4. The second level, referred to as the
high-level trigger (HLT), consists of a farm of processors running a version
of the full event reconstruction software optimized for fast processing, and
reduces the event rate to less than 1kHz before data storage. A more detailed
description of the CMS detector, together with a definition of the coordinate
system used and the relevant kinematic variables, can be found in Ref. [47].

The search is based on a sample of $\Pp\Pp$ collisions at a center-of-mass
energy of 8collected with the CMS detector in 2012 and corresponding to an
integrated luminosity of 19.7. The particle-flow (PF) event algorithm [48]
aims to reconstruct and identify each individual particle with an optimized
combination of information from the various elements of the CMS detector. The
energy of photons is directly obtained from the ECAL measurement, corrected
for zero-suppression effects. The energy of electrons is determined from a
combination of the electron momentum, as determined by the tracker, the energy
of the corresponding ECAL cluster, and the energy sum of all bremsstrahlung
photons spatially compatible with originating from the electron track. The
energy of muons is obtained from the curvature of the corresponding track. The
energy of charged hadrons is determined from a combination of the momentum
measured in the tracker and the matching ECAL and HCAL energy deposits,
corrected for zero-suppression effects and for the response function of the
calorimeters to hadronic showers. Finally, the energy of neutral hadrons is
obtained from the corresponding corrected ECAL and HCAL energy. The missing
transverse momentum, $\ptmiss$, is defined as the magnitude of the vectorial
sum of transverse momenta of all PF candidates within the event.

Events are required to have at least one reconstructed collision vertex within
24 (2)of the mean $\Pp\Pp$ interaction position along the beam axis (in the
plane transverse to the beams). The vertex with the highest sum of $\pt^{2}$
of all the associated tracks is taken to be the primary vertex in the event.

For each event, hadronic jets are clustered from both charged and neutral PF
candidates using the infrared- and collinear-safe anti-algorithm [49] with a
distance parameter of 0.5, as implemented in the FastJet package [50]. Only
those charged PF candidates originating from the primary vertex are included
in the clustering. Corrections based on the jet area [51] are applied to
remove the energy contribution of neutral hadrons from additional $\Pp\Pp$
interactions within the same or nearby bunch crossings (pileup). The jet
momentum is determined as the vectorial sum of all particle momenta in the
jet, and is found in simulation to be within 5 to 10% of the true generator-
level jet momentum, over the whole spectrum and detector acceptance considered
in the analysis. Jet energy corrections are derived from the simulation, and
are confirmed by in situ measurements of the energy balance of dijet,
multijet, $\Pgg$+jet, and leptonically decaying $\PZ$+jet events [52, 53]. Jet
energy corrections are further propagated to . Additional selection criteria
are applied to each event to remove spurious jet-like features originating
from isolated noise patterns in certain HCAL regions [54]. The jet energy
resolution is typically 15% at 10, 8% at 100, and 4% at 1.

Jets originating from quarks are identified using the combined secondary
vertex (CSV) algorithm [55, 56], which takes as inputs the impact parameters
of jet constituents and secondary vertices reconstructed within the jet [57].
We use the “tight” (“medium”) working point of the tagging algorithm, which
corresponds to approximately 50 (70)% b jet tagging efficiency and 0.1–0.2%
(1–2%) light-quark or gluon jet mistag rate for jets with $\pt<300\GeV$. The
tagging efficiency in the simulation is corrected to match the efficiency
measured in data [56].

Simulated Monte Carlo (MC) samples are primarily used to model signal
hypotheses, as background predictions are obtained directly from data. We
consider three models of narrow resonances. Scalar resonance and RS graviton
signal samples are generated at leading order (LO) with 8.212 [58], which also
models the parton shower and hadronization processes, using the CUETP8M1
underlying event tune [59, 60]. The boson samples are generated with 2.3.3
[61], with the parton shower and hadronization modeled with 8. The scalar ()
boson model assumes gluon-gluon (quark-antiquark) production, while the RS
graviton model includes both gluon-gluon and quark-antiquark production
mechanisms; in all three cases, only decays to bottom quarks are simulated.
This is a conservative choice, as in the flavor-universal case decays to charm
quark-antiquark pair would also contribute to the signal acceptance. However,
since the charm quark tagging efficiency by a dedicated tagging algorithm is
relatively low, we ignore this potential increase in the signal acceptance,
leading to a conservative estimate of signal sensitivity. (We estimated the
effect to be only 3–4% in terms of the signal yield for a boson with universal
coupling to quarks.) For all signal hypotheses, the intrinsic resonance width
is negligible compared to the experimental mass resolution. The scalar
resonance and RS graviton signal samples use the NNPDF3.0LO parton
distribution functions (PDFs) [62], while the boson samples are generated with
the NNPDF2.3LO PDF set [63]. Eight mass hypotheses are simulated between 325
and 1200for each of the three signal models.

The QCD multijet background samples are used to guide the analysis
optimization and to study the performance of the tagging algorithm. The
samples are generated at LO using 6.424 [64] with the CTEQ6L1 PDFs [65] and
the underlying event tune Z2* [66, 60]. For all MC samples, the response of
the CMS detector is simulated using [67], including the effects of pileup,
obtained by superimposing additional minimum bias interactions on the hard
scattering, with the multiplicity distribution matching that in data.

Online, events are selected using dedicated triggers that identify jets
originating from quarks at the HLT. At L1, either one jet with $\abs{\eta}<5$
and $\pt>128$or two jets with $\abs{\eta}<1.74$ and $\pt>56$are required. At
the HLT, the jets are reconstructed solely from energy deposits in the
calorimeter towers and augmented with the tracking information within the jet
cone. Two triggers with different requirements on jet and geometrical
acceptance are used, defining the low-mass (SR1) and high-mass (SR2) signal
regions. For SR1, the trigger requires two jets with $\abs{\eta}<1.7$, with
the leading and subleading (in ) jets having $\pt>80$ and 70, respectively.
For SR2, the two jets are required to satisfy $\abs{\eta}<2.2$, with the
leading (subleading) jet $\pt>160$ (125). The HLT tagging algorithm requires
that the ratio of the impact parameter to its uncertainty (including the
uncertainty in the primary vertex position) is large for at least two tracks
within the jet area [56]. At least two of the leading six jets in the event
are required to satisfy the HLT tagging requirements. For signal events
passing the rest of the event selection, the efficiency of the trigger tagging
algorithm is approximately 18% for SR1 and 49% for SR2, as determined from
combined studies based on collision data dominated by QCD multijet events, as
well as on signal and QCD multijet background simulations. The trigger
efficiency stays constant within the uncertainties as a function of the
invariant mass of the two -tagged jets, in the entire range used in the
analysis.

Figure 1: The products of acceptance and efficiency for simulated signal
events in SR1 and SR2, separately for the scalar, , and RS graviton signal
models. The shaded bands represent the statistical uncertainties.

Offline, jets built from PF candidates are used. Events are required to
satisfy $\ptmiss/\sum\ET<0.5$, where $\sum\ET$ is the scalar sum of the
transverse momenta of the PF candidates in the event. This requirement removes
events with the energy of one of the jets significantly mismeasured, as well
as events with large calorimeter noise inside a jet. The two leading jets form
the dijet system. The jets must satisfy the same and $\eta$ requirements as in
the corresponding HLT trigger. The pseudorapidity difference between the two
jets must be less than $1.3$. This requirement reduces the QCD multijet
background considerably, while retaining high signal efficiency [13, 23]. One
of the two leading jets is required to pass the tight working point of the CSV
algorithm, while the other must pass the medium CSV working point. Finally,
the dijet invariant mass ($m_{\text{jj}}$) range is set to 296–1058for SR1,
and 526–1607for SR2. These two search regions are used to probe signal masses
in the range 325–700 and 700–1200, respectively, with the boundary chosen in
the vicinity of the intersection of the expected limits in these two regions
for all three resonance spins.

The product of acceptance and efficiency ($\sigma\mathcal{A}$) for simulated
signal events are shown in Fig. 1. For SR1 (SR2), these range from 1.2 to 2.9%
(1.6 to 4.5%), with small differences between models due to differences in the
geometrical acceptance, defined by the rapidity requirements on the two
leading jets. At high masses (above 750), $\sigma\mathcal{A}$ drops because of
the reduced tagging efficiency for high-jets.

Figure 2: The dijet invariant mass distributions in SR1 (left) and SR2
(right), shown with the background prediction derived from a fit using an
empirical function under the background-only hypothesis. Representative
examples of signal distributions are also shown, each normalized to a visible
cross section of 1pb. The bottom panels show the difference between the data
and the background estimate, divided by the statistical uncertainty in the
estimated background.

The background estimate is obtained from a binned (with 1bins), extended
maximum likelihood [68] fit to the $m_{\text{jj}}$ spectrum in data using an
empirically determined function. Several families of steeply falling functions
commonly used in similar searches are considered, and the best fit function is
chosen using an $F$-test [69] based on the $\chi^{2}$ per degree of freedom of
the fit. The function chosen is:
$\rd\sigma/{\rd}x=\epsilon_{\text{trig}}(x)p_{0}(1-x)^{p_{1}}x^{-p_{2}-p_{3}\log(x)}$,
where $x=m_{\text{jj}}/\sqrt{s}$, and $\epsilon_{\text{trig}}(x)$ is a sigmoid
function describing the efficiency of the requirements of the trigger. The
parameters of the sigmoid function are determined in events collected with
triggers requiring a single isolated muon, and are fixed in the background
fit. The trigger turn-on effect is sizable only at the lower end of SR1, with
the trigger inefficiency being 1.8% for $m_{\text{jj}}=296\GeV$ and less than
0.1% for $m_{\text{jj}}>380\GeV$. The $m_{\text{jj}}$ distributions of the
signal hypotheses are modeled using convolutions of a Gaussian and an
exponential function [70]. The signal shapes for masses between two adjacent
simulated mass points are derived via a linear interpolation of the fit
function parameters. The typical width of the Gaussian core of a signal
resonance is 10–15%, depending on the resonance spin and production mechanism,
as well as on the resonance mass.

Extensive studies of a possible systematic bias from the choice of the
functional form of the background estimate are performed with alternative fit
functions, with or without signal injection. The shapes obtained from
background-only fits to the data with the alternative functions are used to
generate pseudo-data sets. Each pseudo-data set has a total number of events
randomly drawn from a Poisson distribution with the mean equal to the yields
observed in data. In the set of studies with signal injection, the pseudo-data
sets are generated from a signal plus background model. In these studies, the
injected signal cross section corresponds approximately to the expected 95%
confidence level (CL) cross section limits discussed below. The generated
$m_{\text{jj}}$ spectra are then fitted with the sum of chosen background
function and a signal model, and the signal cross section is extracted.
Distributions of the difference between the fitted and injected signal cross
sections divided by the fitted uncertainty are constructed, and their shapes
are found to be consistent with a normal distribution with the mean within 0.5
of zero and the width consistent with unity. Thus, we conclude that any
possible systematic bias from the choice of the functional form is small
compared to the statistical uncertainty of the fit, and use the latter as the
only uncertainty in the background prediction.

Figure 2 shows the $m_{\text{jj}}$ distributions in data in SR1 and SR2,
fitted with the background-only hypothesis, together with representative
examples of signal distributions normalized to a visible cross section, ,
fiducial $\sigma\mathcal{A}$ of 1pb. For presentation purposes, the data are
binned with a bin width approximating the experimental dijet mass resolution.

Systematic uncertainties are assigned to the simulated signal to account for
observed differences between simulation and data. Jet energy scale and
resolution uncertainties of 1 and 10% [53] in the dijet invariant mass,
respectively, are included as the uncertainties in the fitted signal
parameters. The following four sources of uncertainty in the signal yield are
considered. Scale factors are applied to account for mismodeling of the
tagging efficiency in simulation, leading to a 5–15% [55, 56] uncertainty,
depending on the signal mass. An uncertainty of 10% is assigned to the tagging
efficiency in the HLT (as measured from data collected with unbiased prescaled
triggers). An uncertainty of 2–5% is assigned to account for the effect of the
choice of PDFs on the signal acceptance, following the PDF4LHC prescription
[71, 72]. Finally, an uncertainty of 2.6% is assigned to the integrated
luminosity measurement [73].

Figure 3: Observed and expected 95% CL upper limits on the product of cross
section and branching fraction to bottom quark-antiquark pairs for a scalar
resonance (left), boson (middle), and RS graviton (right) signal models, as
functions of resonance mass. The discontinuity in the limits at 700is
associated with a change in the acceptance from SR1 to SR2.

Figure 4: Left: The 95% CL upper limits (solid line) on the universal coupling
$g^{\prime}_{\PQq}$ between the leptophobic boson and quarks. Limits from
other experiments [2, 8, 9, 18] and earlier CMS analyses [33, 34, 37], are
also shown, along with an indirect constraint from the $\PZ$ boson width [74].
Right: Expected (dashed lines) and observed (solid lines) 95% CL upper limits
on the simplified model variable $\zeta$. The limits are shown for
$\PQu\PAQu\to\cPZpr$ and $\PQd\PAQd\to\cPZpr$ individually, as well as for
$\Pp\Pp\to\cPZpr$, assuming a universal quark coupling. The $\zeta$ values for
the boson model with $g^{\prime}_{\PQq}=0.25$ are also shown. The hatched red
band represents the envelope of limits for theoretical models that predict an
$s$-channel production of a resonance with arbitrary couplings to up and down
quarks. The discontinuity in the limits at 700is associated with a change in
the acceptance from SR1 to SR2.

For each signal hypothesis, the dijet invariant mass spectrum is fit with a
signal plus background hypothesis, where the parameters of the background
function are freely floating. No significant excesses over the background-only
hypothesis are observed. We set limits on the production of narrow resonances
using the CLs criterion [75, 76, 77], with an asymptotic approximation [78]
for the likelihood ratio used as a test statistic, and log-normal (Gaussian)
constraints used to account for the systematic uncertainties in the signal and
background yields (shapes). In Fig. 3, the results are interpreted as upper
limits at 95% CL on the product of cross section and branching fraction to
bottom quark-antiquark pairs, $\mathcal{B}(\bbbar)$. The observed limits
improve on the previously obtained limits on the resonances for masses below
1.1, and extend below the threshold, which is important to restrict the models
with resonances coupled preferentially to the third-generation particles.

The limits on the boson model are further interpreted in the context of a
simplified model of a leptophobic vector resonance with a universal coupling
to quarks $g^{\prime}_{\PQq}$ that is related to the coupling of Ref. [79] by
$g^{\prime}_{\PQq}=g_{\mathrm{B}}/6$. The limits on $g^{\prime}_{\PQq}$ are
shown in Fig. 4 (left), along with limits from other experiments [2, 8, 9, 18]
and earlier CMS analyses [33, 34, 37]. The current results improve on the
existing limits in the mass range $325<m_{\cPZpr}<500\GeV$, where
$g^{\prime}_{\PQq}$ values above 0.11–0.18 are excluded. We note that the
narrow-width approximation used in setting cross section limits in this
analysis that are further translated into $g^{\prime}_{\PQq}$ limits is valid
only for $g^{\prime}_{\PQq}$ values $\lesssim$0.7. This upper limit
corresponds to a resonance width of about 25% of its mass, , comparable with
the instrumental resolution. Consequently, we truncate the $y$ axis of Fig. 4
(left) at this value of the coupling.

Following the method described in Ref. [80], the limits on the boson model are
further interpreted as limits on the variable
$\zeta=[\sum_{ij\;\in\;I}\mathcal{B}(\cPZpr\to
ij)]\mathcal{B}(\cPZpr\to\bbbar)\Gamma_{\cPZpr}/m_{\cPZpr}$, where
$\Gamma_{\cPZpr}$ is a width of the resonance, $\mathcal{B}$ is a branching
fraction, and $I$ represents the set of production modes $ij\to\cPZpr$, with
$i$ and $j$ being the corresponding partons. The $\zeta$ variable provides a
model-independent description of the generic $s$-channel production of narrow-
width resonances and can be used for a variety of theoretical interpretations
of experimental limits on the production of such resonances decaying into
various final states. The limits are shown in Fig. 4 (right) for the model
with a universal quark coupling, as well as for up and down quark production
modes individually. The limits are determined using the narrow-width
approximation, which corresponds to a conservative interpretation [81]: for
the boson model with $g^{\prime}_{\PQq}=0.25$, the $\zeta$ limits computed
with the resonance width taken into account are lower by 0.3 (4.7)% at
$m_{\cPZpr}=400$ (1200). The $\zeta$ interpretation can be used, , to convert
the $g^{\prime}_{\PQq}$ limits in Fig. 4 to limits on the coupling
$g^{\prime}_{\PQd}$ for a boson model with coupling only to down-type quarks.
Taking into account the different branching fractions and the widths of the
two models,
$g^{\prime}_{\PQd}=g^{\prime}_{\PQq}[\zeta(\PQd\PAQd\to\cPZpr\to\bbbar)/\zeta(\Pp\Pp\to\cPZpr\to\bbbar)]^{1/2}$.

In summary, a search for new resonances decaying to bottom quark-antiquark
pairs produced in 8TeV proton-proton collisions has been presented. Using
triggers that identify jets originating from bottom quarks, the search probes
signal masses as low as 325. No statistically significant excesses above the
background predictions are observed in the entire invariant mass range
studied, 325–1200. Upper limits are set on the production cross section of
scalar, vector, and tensor resonances. The limits are also interpreted in the
context of a simplified model of a leptophobic boson with a universal coupling
$g^{\prime}_{\PQq}$ to quarks. Values of $g^{\prime}_{\PQq}$ above 0.11–0.18
are excluded for boson masses below 500, improving on the previous best limits
in this mass range, which date back to the CDF experiment. The first
experimental limits on the parameter $\zeta$ of a simplified $s$-channel
resonance framework [80] have been obtained, making possible the
reinterpretation of the limits in a variety of theoretical models
corresponding to different resonance production and decay mechanisms.
