# Search for dijet resonances using events with three jets in proton-proton
collisions at $\sqrt{s}=13\TeV$

###### Abstract

A search for a narrow resonance with a mass between 350 and 700, and decaying
into a pair of jets, is performed using proton-proton collision events
containing at least three jets. The data sample corresponds to an integrated
luminosity of 18.3recorded at $\sqrt{s}=13\TeV$ with the CMS detector. Data
are collected with a technique known as “data scouting”, in which the events
are reconstructed, selected, and recorded at a high rate in a compact form by
the high-level trigger. The three-jet final state provides sensitivity to
lower resonance masses than in previous searches using the data scouting
technique. The spectrum of the dijet invariant mass, calculated from the two
jets with the largest transverse momenta in the event, is used to search for a
resonance. No significant excess over a smoothly falling background is found.
Limits at 95% confidence level are set on the production cross section of a
narrow dijet resonance and compared with the cross section of a vector dark
matter mediator coupling to dark matter particles and quarks. Translating to a
model where the narrow resonance interacts only with quarks, upper limits on
this coupling range between 0.10 and 0.15, depending on the resonance mass.
These results represent the most stringent upper limits in the mass range
between 350 and 450obtained with a flavor-inclusive dijet resonance search.

##  0.1 Introduction

Many models of new physics predict the existence of new massive particles
coupled to quarks. The production and decay of these particles into two jets,
known as dijets, have been searched for since the first high-energy hadron
colliders came into operation [1, 2, 3, 4, 5, 6, 7, 8, 9]. In some models,
these particles act as mediators linking the standard model (SM) to new
physics sectors containing dark matter (DM) particle candidates [10, 11, 12,
13]. New mediators interacting with both quarks and DM particles () have been
searched for using different methods: in the direct searches for DM, by
measuring the recoil of an SM particle caused by the scattering with a DM
particle ($\PGc\PQq\to\PGc\PQq$, $t$-channel) [14, 15, 16, 17, 18, 19, 20, 21,
22, 23, 24]; with astrophysics detectors, by looking for SM particles produced
through the annihilation of DM particles ($\PGc\PGc\to\PQq\PQq$, $s$-channel)
[25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39]; and at hadron
colliders, by detecting the momentum imbalance due to the production of DM
particles ($\PQq\PQq\to\PGc\PGc$, $s$-channel) [40, 41, 42, 43, 44, 45, 46].
The search for dijet resonances at hadron colliders ($\PQq\PQq\to\PQq\PQq$,
$s$-channel) can be compared with such DM searches and the results are
particularly sensitive for models where the decay of the mediator into DM
particles is forbidden for kinematic reasons. The search for dijet resonances
is also sensitive to the signals predicted by other models [47, 48, 49, 50,
51, 52, 53, 54, 55, 56, 57].

Experiments at the CERN LHC have used various techniques to search for
resonances in the dijet invariant mass spectrum. From searches where both jets
are individually resolved, the ATLAS and CMS Collaborations have set limits
for resonances with masses above 450 and 600, respectively, in
$\sqrt{s}=13\TeV$ proton-proton collisions [58, 59, 60], and above 250 and
500, respectively, in 8collisions [61, 62]. In the sub-mass range, another
search by the ATLAS Collaboration at 13for dijet resonances, produced in
association with a photon from initial-state radiation, has set limits in the
mass region between 225 and 1100[63]. A search by the CMS Collaboration at
8for resonances decaying into two bottom quarks, experimentally identified as
-tagged jets, has set limits in the mass range of 325–1200[64]. Finally, the
ATLAS and CMS Collaborations have set limits in the mass range below 220 and
450, respectively, from searches for Lorentz-boosted resonances decaying into
a quark-antiquark pair reconstructed as a single jet [65, 66, 67].

This paper presents a search for a dijet resonance in three-jet events that is
sensitive to narrow resonances with mass between 350 and 700 . The search is
based on data from $\Pp\Pp$ collisions at $\sqrt{s}=13\TeV$ collected in 2016,
corresponding to an integrated luminosity of 18.3. To obtain a large trigger
efficiency in the mass range of $350$–700 , we select a three-jet final state
and utilize a special high-rate trigger with low jet thresholds. This trigger
uses a technique known as “data scouting” described in Section 0.3. This
search is limited to data collected in the year 2016 in order to take
advantage of the low trigger thresholds used in that data period. After 2016,
these thresholds were raised in order to limit the trigger rate increase due
to the larger instantaneous luminosity and pileup.

##  0.2 The CMS detector

A 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. [68]. 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.
Muons are detected in gas-ionization chambers embedded in the steel flux-
return yoke outside the solenoid.

The jets used by this analysis are calorimeter-based jets that are
reconstructed from the energy deposits in the calorimeter towers, clustered
using the anti-algorithm [69, 70] with a distance parameter of 0.4. In this
process, the contribution from each calorimeter tower is assigned a momentum,
the absolute value and the direction of which are found from the energy
measured in the tower, and the coordinates of the geometrical center of the
tower. The raw jet energy is obtained from the sum of the tower energies, and
the raw jet momentum from the vectorial sum of the tower momenta. The raw jet
energies are then corrected to establish a uniform relative response of the
calorimeter in pseudorapidity $\eta$ and a calibrated absolute response in
transverse momentum . The calorimetric jet energy resolution is typically 40%
at a of 10 , 12% at 100 , and 5% at 1 , resulting in a calorimetric dijet mass
resolution of about 10% for resonance masses between 350 and 700 . Events of
interest are selected using a two-tiered trigger system [71]. 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, known 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 around 1kHz before data storage.

##  0.3 Data and simulated event samples

We selected events requiring ${\HT>240\GeV}$ at the L1 trigger and
$\HT>250\GeV$ at the HLT, where is the scalar sum of jets with $\pt>40\GeV$
and $\abs{\eta}<2.5$. The rate of this trigger was about 4kHz at an
instantaneous luminosity of $1\times 10^{34}\unit{cm$^{-2}$s$^{-1}$}$. The
amount of data generated by such a high-rate trigger alone using the standard
data-taking format would have saturated the computing and storage systems of
the CMS experiment. For this reason, we used a special data-taking technique,
which consisted of saving only the calorimeter-based jets reconstructed by the
HLT, instead of the full detector readout. The size of this reduced data
format is about 0.5% of the full event size. This technique is known as “data
scouting” and was used in previous CMS dijet resonance searches [62, 60].

Data scouting allows the analysis of a very large rate of data passing the HLT
trigger, only limited by the overall rate of the L1 trigger. To keep a
constant rate, the L1 trigger threshold was raised from 240 to 360as the
instantaneous luminosity increased. This search is limited to data collected
in 2016 with the lower L1 trigger threshold $\HT>240\GeV$, in order to obtain
the maximum sensitivity for low mass resonances. From a sample of events
collected with a minimum-bias trigger and passing the selection discussed
below, we measured a trigger efficiency larger than 99% for a dijet invariant
mass greater than 290.

Signal events corresponding to a narrow vector resonance decaying into quark-
antiquark pairs were generated using the version 2.2.2 generator at leading
order [72, 73], with the 8.205 generator [74] incorporating the CUETP8M1
underlying event tune [75] providing the description of fragmentation and
hadronization. The generated resonance width is negligible compared to the
experimental dijet mass resolution, which is about 10%. The detailed
simulation of the CMS detector response is performed using the package [76].
The simulated signal events include multiple overlapping $\Pp\Pp$ interactions
per bunch crossing (pileup) as observed in the data. Additionally, to provide
a framework for interpreting the results in terms of a DM mediator, signal
cross sections were computed at leading order with for a vector boson decaying
into a quark-antiquark pair, with coupling to quarks $g_{\Pq}=0.25$, coupling
to DM particles $g_{\text{DM}}=1.0$, and the mass of DM particles 1. The
NNPDF2.3LO [77] parton distribution functions were used.

##  0.4 Event reconstruction and selection

The discriminating variable in this analysis is the invariant mass of the two
jets originating from the resonance decay. This variable is calculated using
jets, reconstructed at the HLT from energy deposits in the calorimeter, and
passing the selection $\pt>30\GeV$ and $\abs{\eta}<2.5$. Spurious jets
originating from instrumental noise are rejected by requiring each jet to be
detected by both ECAL and HCAL, with at least 5% of the jet energy in each of
the two types of calorimeter. We form “wide jets”, by clustering the jets
already reconstructed by the HLT, using the anti-algorithm with a distance
parameter of 1.1. This algorithm improves the dijet mass resolution and the
resonance search sensitivity, by recombining jets from hard final-state
radiation to obtain a reduced number of wide jets. A similar algorithm using a
merging distance of
${\DR=\sqrt{\smash[b]{(\Delta\eta)^{2}+(\Delta\varphi)^{2}}}<1.1}$ was
employed in previous CMS searches [60, 62], but it only reconstructed two wide
jets per event. The wide-jet calibrations for the 2016 data scouting sample
were already obtained in the low-mass dijet search of Ref. [60], and therefore
we apply the same calibrations. We require at least three wide jets, each with
$\pt>72\GeV$, in order to select events that have large and pass the trigger
selections. This requirement is particularly effective in selecting events
with low dijet invariant mass, which would be rejected if only two jets were
required. Applying a common threshold to the of the three jets enabled us to
minimize the value of the lowest resonance mass to which we are sensitive. The
threshold of the three-jet selection has been chosen with a method that is
explained in the next section. Finally, the two leading wide jets are required
to have $\abs{\eta_{1}-\eta_{2}}<1.1$ to reduce the quantum chromodynamics
multijet background, which is dominated by $t$-channel production of jets.

Since we require at least three wide jets in the event, there are multiple
ways to select the dijet system, , the pair of wide jets originating from the
resonance decay. We select as the dijet the two wide jets with the largest and
the next-to-largest in the event. This selection is correct in 70 (50)% of
simulated signal events with a resonance mass of 700 (350). Wrong combinations
arise because either an energetic initial-state radiation jet is included in
the dijet selection, or an energetic jet from final-state radiation is emitted
with a distance $\DR>1.1$ from the leading jets and therefore excluded from
the reconstruction of the two leading wide jets. We investigated alternative
criteria to select the dijet, such as choosing the jet pair with the largest
norm of the vectorial sum . We found that such alternative criteria do have
better performance if the resonance is greater than half the mass, but worse
performance for this search. This is because, for accepted events, the of the
resonance is about 150, which is less than half the resonance mass considered
in this search.

##  0.5 Dijet mass spectrum fit

Figure 1 shows the dijet mass ($m_{\mathrm{jj}}$) spectrum. The background is
modeled with the following analytic function,

$\frac{\rd\sigma}{\rd
m_{\mathrm{jj}}}=\frac{p_{0}(p_{2}x-1)}{x^{p_{1}+p_{3}\log{x}+p_{4}\log^{2}{x}}},$
(1)

where $x$ is defined as $m_{\mathrm{jj}}/\sqrt{s}$, and $p_{0}$, $p_{1}$,
$p_{2}$, $p_{3}$, and $p_{4}$ are free parameters of the fit. This function is
similar to that used by previous dijet searches [60, 58, 59, 62, 61], with a
modification to the numerator. The new parameterization better fits the shape
of the dijet mass spectrum for three-jet events, which includes the effect of
a small inefficiency to pass the trigger for events at the lowest values of
dijet mass. The function has been chosen from a pool of functions using a
Fisher test [78] with a $95\%$ confidence level (). The pool of functions is
obtained by changing the number of degrees of freedom of the polylogarithmic
function in the exponent of the denominator of Eq. (1). We perform a maximum
likelihood fit of the function in Eq. (1) to our data in the mass range
${290<m_{\mathrm{jj}}<1000\GeV}$. The chi-square per number of degrees of
freedom of the fit is $\chi^{2}/\mathrm{NDF}=19.3/13$, corresponding to a
p-value of $0.11$. Figure 1 also shows the expected dijet mass distributions
of a resonance signal for three different values of resonance mass. The data
distribution is well modeled by the background parameterization and there is
no evidence for a dijet resonance.

Figure 1:  Dijet mass spectrum (points) compared to a fitted parameterization
of the background (solid curve). The background fit is performed in the range
$290<m_{\mathrm{jj}}<1000\GeV$. The horizontal bars show the widths of each
bin in dijet mass. The dashed lines represent the dijet mass distribution from
400, 550, and 700resonance signals expected to be excluded at 95% by this
analysis. The lower panel shows the difference between the data and the fitted
parametrization, divided by the statistical uncertainty of the data.

The dijet mass bin widths in Fig. 1 are the same as in the previous dijet
searches, except for the first bin which is more narrow, starting at a dijet
mass value of 290. This lower bound of the fit range and the jet threshold for
the three-jet selection are determined in the following way. We measure the
distribution of the dijet mass in a signal-depleted region defined by
replacing the requirement ${\abs{\eta_{1}-\eta_{2}}<1.1}$ with the requirement
${\abs{\eta_{1}+\eta_{2}}<1.1}$. The dijet mass in the signal-depleted region
is calculated after flipping the sign of $\eta$ of the second jet—the sign of
the $z$ component of the momentum of the subleading jet is reversed and then
the dijet mass is calculated. For background events, the dijet mass
distribution in the signal-depleted region, so calculated, is closely similar
to the dijet mass distribution in the signal region because the variables
$\eta_{1}-\eta_{2}$ in the signal region and $\eta_{1}+\eta_{2}$ in the
signal-depleted region have approximately the same uniform distribution
between $-1.1$ and 1.1. The signal-depleted region contains about the same
number of background events and 50% fewer signal events, and 35% of the
observed events in the signal-depleted region are also in the signal region.
Small data-driven corrections, which change the observed number of events by
less than 5%, are applied to the dijet mass distribution in the signal-
depleted region to make it the same as the background distribution in the
signal region. These corrections, which are applied as a function of the
product of the two largest values of jet $\pt$ in the event, are obtained by
fitting an analytic function describing this product to the ratio of the
numbers of events passing the signal selection to the number of events passing
the signal-depleted selection. The lower edge of dijet mass included in the
search, 290, has been chosen to be the lowest value of the corrected dijet
mass in the signal-depleted region for which the fit of the background
parameterization has a Kolmogorov–Smirnov (KS) probability [79, 80, 81] larger
than 33%. The threshold of the three-jet selection, 72, has been chosen to
obtain the lowest possible value for the corrected dijet mass in the signal-
depleted region that could be included in the fit and satisfy the same KS
test. We verified that an injected signal with a strength corresponding to the
95% expected upper limit does not change the choice of the fit range and the
three-jet selection.

##  0.6 Systematic uncertainties

The asymptotic approximation [82] of the modified frequentist method [83, 84]
is utilized to set upper limits on signal cross sections, following the
prescription described in Ref. [85]. We use the profiled likelihood ratio as
test statistic. The likelihood is the product of the Poisson probabilities for
each of the bins in Fig. 1. The expected background yield of each bin is
determined from the analytic function described in Eq. (1). The five
parameters of the analytic function are profiled and their uncertainties from
the fit to data are the dominant uncertainties. The shapes of the dijet mass
distributions for signals are obtained from simulations. The systematic
uncertainties affecting the signal shape and normalization have a minor impact
and are incorporated into the likelihood function via nuisance parameters with
log-normal probability distributions. We account for the uncertainty of 2% in
the jet energy scale [86] by shifting the dijet mass of the signal
distribution by $\pm 2\%$. The effect of the jet energy resolution uncertainty
is included by varying the width of the signal distribution by $\pm 10\%$
[86]. The signal acceptance depends significantly on the presence of a jet
from initial-state or final-state radiation. We estimated the uncertainty of
the simulation related to this dependence by modifying by a factor of two both
the renormalization ($\mu_{R}$) and the factorization scales ($\mu_{F}$) of
the initial-state and final-state radiation using the method described in Ref.
[87]. This uncertainty has a negligible effect on the shape of the dijet mass
distribution of the signal, and changes the normalization by 10%. The
uncertainty in the integrated luminosity is 2.5% [88] and affects directly the
signal normalization. The systematic uncertainty due to the choice of the
background function has been estimated by measuring the signal yield in
pseudo-data spectra generated using alternative background functions. The
measured cross section in each case is the same as that of the injected
signal, and this systematic uncertainty is found to be negligible. We tested
the capability of the alternative functions to fit the multijet background by
fitting the signal-depleted region described in Section 0.5. The systematic
uncertainties related to pileup, parton distribution functions, underlying
events, and parton shower models are also found to be negligible.

##  0.7 Results

Figure 2 shows, as a function of resonance mass, observed and expected upper
limits at 95% on the product of the cross section, branching fraction, and
acceptance of a narrow vector resonance decaying to jets.

Figure 2: Upper limits at 95% on the product of the cross section, branching
fraction, and acceptance as a function of resonance mass for a narrow vector
resonance decaying into a pair of quark jets. The acceptance is calculated for
the analysis selection, namely three wide jets with $\pt>72\GeV$ and
$\abs{\eta}<2.5$, and ${\abs{\eta_{1}-\eta_{2}}<1.1}$. The observed limits
(solid curve), expected limits (dashed curve) and their variation at the 1 and
2 standard deviation levels (shaded bands) are shown. The dashed-dotted curve
shows the expected cross section times acceptance for a DM mediator (see
text).

resonance mass. The acceptance is calculated using signal simulations for the
analysis selection, namely three wide jets with ${\pt>72\GeV}$ and
${\abs{\eta}<2.5}$, and ${\abs{\eta_{1}-\eta_{2}}<1.1}$. The errors are
dominated by the uncertainty related to the modeling of the jet radiation used
in signal simulations. We estimated this uncertainty by modifying by a factor
of two both the renormalization ($\mu_{R}$) and the factorization scales
($\mu_{F}$) of the initial-state and final-state radiation [87].  Resonance

0.9)\%$ $(10.9\pm 1.1)\%$ $(13.6\pm 1.4)\%$

Limits are presented for resonance masses between 350 and 700, for which the
acceptance of the dijet mass requirement ${290<m_{\mathrm{jj}}<1000\GeV}$ is
large enough to conduct the search. Figure 3 shows that the 95% upper limits
on the coupling $g^{\prime}_{\Pq}$ of a vector resonance that decays only to
quarks, defined according to the convention of Ref. [89], are between 0.10 and
0.15.

Figure 3: Upper limits at 95% on the universal quark coupling
$g^{\prime}_{\Pq}$, as a function of resonance mass, for a narrow vector
resonance that only couples to quarks. The observed limits (solid curve),
expected limits (dashed curve) and their variation at the 1 and 2 standard
deviation levels (shaded bands) are shown. The dashed-dotted curve shows the
coupling strength for which the cross section for dijet production in this
model is the same as for a DM mediator (see text).

Figures 2 and 3 compare the upper limits on the cross section and the coupling
$g^{\prime}_{\Pq}$, respectively, with the predictions of a model with a DM
mediator that decays to DM particles with masses of 1, and also decays to
quarks. This analysis excludes a benchmark model of such a DM mediator with
coupling to quarks $g_{\Pq}=0.25$ and coupling to DM particles
$g_{\text{DM}}=1$, over the complete mass range 350 to 700. In our notation,
$g^{\prime}_{\Pq}$ is the coupling for a model in which the resonance couples
to quarks only, and $g_{\Pq}$ is the coupling to quarks for a model in which
the resonance also couples to DM particles. We convert $g_{\Pq}$ into
$g^{\prime}_{\Pq}$ using the following relationship

$g^{\prime}_{\Pq}=\frac{g_{\Pq}}{\sqrt{1+1/\left(3N_{\PQq}(M_{\text{med}})g_{\Pq}^{2}\right)}}$
(2)

where $N_{\PQq}(M_{\text{med}})$ is the effective number of quarks

$N_{\PQq}(M_{\text{med}})=\sum_{q}\left(1-4\frac{m^{2}_{q}}{M_{\text{med}}^{2}}\right)^{1/2}\left(1+2\frac{m^{2}_{q}}{M_{\text{med}}^{2}}\right)$
(3)

and the index $q$ runs over the quark flavors (, , , , , ) having
$m_{q}<M_{\text{med}}/2$ [60, 11].

##  0.8 Summary

A search for a narrow vector resonance of mass between 350 and 700 decaying
into two jets has been performed in events containing at least three jets
using proton-proton collision data at $\sqrt{s}=13\TeV$ at the LHC
corresponding to an integrated luminosity of 18.3. The dijet mass distribution
of the two leading jets is smooth, and there is no evidence for a resonance.
Upper limits at 95% confidence level are set on the product of the cross
section, branching fraction, and acceptance as a function of resonance mass.
This search excludes a simplified model of interactions between quarks and
dark matter particles of mass 1, where the interactions are mediated by a
vector particle with mass between 350 and 700, for coupling strengths of
$g_{\Pq}=0.25$ and $g_{\text{DM}}=1$. Upper limits between 0.10 and 0.15 are
also set on the coupling to quarks $g^{\prime}_{\Pq}$ for a vector particle
interacting only with quarks. These results represent the most stringent upper
limits in the mass range between 350 and 450obtained with a flavor-inclusive
dijet resonance search.
