This Letter describes a model-independent search for the production of new resonant states in photonþ jet events in 2:11 fb1 of proton-proton collisions at pffiffiffis¼ 7 TeV. We compare the photonþ jet mass distribution to a background model derived from data and find consistency with the background-only hypothesis. Given the lack of evidence for a signal, we set 95% credibility level limits on generic Gaussian-shaped signals and on a benchmark excited-quark (q) model, excluding 2 TeV Gaussian resonances with cross section times branching fraction times acceptance times efficiency near 5 fb and excluding q masses below 2.46 TeV, respectively.

In the standard model (SM), proton-proton (pp) colli-sions do not produce photonþ jet pairs through a reso-nance. Direct photonþ jet production occurs at tree level via Compton scattering of a quark and a gluon or through quark-antiquark annihilation, the former accounting for the majority of direct photonþ jet production at all center-of-mass energies. Events with a high transverse momentum photon and one or more jets can also arise from radiation off final-state quarks or from multijet processes where dijet or higher-order events produce secondary photons during fragmentation of the hard-scatter quarks and gluons [1–4]. The photonþ jet invariant mass (mj) [5] distribution
resulting from this mixture of processes is smooth and rapidly falling, constituting a promising place to look for resonances.
Despite many possible exotic production mechanisms such as excited quarks [6,7], quirks [8–10], Regge excita-tions of string theory [11–14], and topological pions [15], the most recent searches for photonþ jet resonances were published a decade ago [16–19]. The previous most sensi-tive search for new phenomena in the photonþ jet final state places limits on effective signal cross section, cross section times branching fraction times acceptance times efficiency, of the order of 1 pb and on excited-quark masses up to 460 GeV at the 95% confidence level [16].
This Letter describes a general search for resonant s-channel photonþ jet production in 2:11 fb1of pp col-lisions at a center-of-mass energy pffiffiffis¼ 7 TeV with the ATLAS detector. It follows earlier measurements of iso-lated photon differential cross sections at the Large Hadron Collider (LHC) [20,21]. The entire mj distribution is fit
to a smooth function to obtain the background to this search. We look for evidence of a narrow resonance, not much wider than the detector mass resolution. This search extends the method used in the search for resonant dijet production [22] to handle the more diverse mixture of processes contributing to the mj distribution. In the
ab-sence of a signal, we use Bayes’ theorem to set limits on Gaussian-shaped resonances and on a benchmark excited-quark (q) model [6,7].
In the excited-quark model studied here, the LHC could produce single qstates with vectorlike couplings to the W and Z gauge bosons via the absorption of a gluon by a quark. As in Ref. [7], we define the model by one parame-ter, the excited-quark mass mq, setting the compositeness
scale equal to mq and SU(3), SU(2), and U(1) coupling
multipliers fs¼ f ¼ f0¼ 1. At mq ¼ 2:5 TeV, this
gives branching fractions for u! ug and u ! u of 0.85 and 0.02, respectively. The corresponding branching fractions for dquarks are 0.85 and 0.005, respectively. We do not make any further assumptions about higher-order corrections or the excited-quark dynamics and neglect scale uncertainties and uncertainties on parton distribution functions in order to provide a convenient benchmark process for theoretical reinterpretation.
We simulate the SM direct photon processes and the q model with PYTHIA 6.4.25[23] using theAMBT1 tune [24], MSTW2007 parton distribution functions [25], and a
GEANT4-based detector simulation [26,27]. Supplementary studies of the background shape function are performed with next-to-leading-orderJETPHOX 1.3.0 [1,2]. Additional inelastic pp interactions, termed pileup, are included in the event simulation, distributed so as to reproduce the number of collisions per bunch crossing in the data. The mean number of pileup interactions is approximately 6.
A detailed description of the detector is available in Ref. [28]. Photons are detected by a lead–liquid-argon sampling electromagnetic calorimeter (EMC) with an

accordion geometry. In front of the EMC, the inner detec-tor allows an accurate reconstruction of tracks from the primary pp collision point and also from secondary vertices, permitting an efficient reconstruction of photon conversions in the inner detector up to a radius of 80 cm. For jj < 1:37 [29], an iron–scintillator-tile calorimeter behind the EMC provides hadronic coverage. The endcap and forward regions, 1:5 < jj < 4:9, are instrumented with liquid-argon calorimeters for both electromagnetic and hadronic measurements. For further details relevant to photon identification and measurement, see Ref. [20]. For details relevant to jet detection and measurement, see Ref. [30]. Events are collected with a trigger requiring at least one photon candidate with a transverse momentum (pT) above 80 GeV. The integrated luminosity of the sample isð2:11 0:08Þ fb1[31,32].
Events containing at least one photon and at least one jet are selected for analysis. Each event must have a primary vertex with at least five charged-particle tracks with pT>400 MeV. Multiple vertices can appear when pileup interactions occur for the same bunch crossing. If more than one vertex is found, the primary vertex is taken as the vertex with the highest scalar sum p2T of associated tracks. Photon candidates with pT>85 GeV andjj < 1:37 and jet candidates with pT>30 GeV and jj < 2:8 are used. These objects are identified using criteria that closely follow those applied in the isolated photon cross section measurement [20] and dijet resonance search [22]. Subleading photons or jets are allowed; when more than one photon or jet is found, the highest pT candidates are selected to constitute the photonþ jet pair.
Jets are reconstructed from clusters of calorimeter cells using the anti-kt clustering algorithm [33] with radius parameter R¼ 0:6. Jet energies are corrected to the had-ronic scale [30,34]. Jet candidates are rejected in regions of the calorimeter where the jet energy is not yet measured in an optimal way. Candidates consistent with spurious calo-rimeter noise or energy spikes are also rejected.
Photon candidates are reconstructed from clusters in the electromagnetic calorimeter and tracking information provided by the inner detector. They satisfy standard ATLAS selection criteria that are designed to reject instru-mental backgrounds from hadrons [20]. The photon can-didates must meet pT- and -dependent requirements on hadronic leakage, shower shapes in the electromagnetic strip layer, and shower shapes in the second sampling layer of the electromagnetic calorimeter. Inner detector tracking information is used to reject electrons and to recover photons converted to eþe pairs. Energy calibrations are applied to photon candidates to account for energy loss in front of the electromagnetic calorimeter and for both lat-eral and longitudinal leakage. Events are discarded if the leading photon appears in calorimeter cells affected by noise bursts or transient hardware problems.
These photon identification criteria reduce instrumental backgrounds to a negligible level, but much of the sub-stantial background from secondary ( jet fragmentation) photons remains. We reduce this background with require-ments on nearby calorimeter activity. Associated ‘‘isola-tion’’ calorimeter energy near the photon candidate is calculated by summing the transverse momentum as mea-sured in electromagnetic and hadronic calorimeter cells inside a cone of radiusR ¼pffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiðÞ2þ ðÞ2 ¼ 0:4 cen-tered on the photon cluster, but excluding the energy of the photon cluster itself. The isolation energy is corrected on an event-by-event basis for the ambient energy density due to pileup and the underlying event. This isolation energy is required to be less than 7 GeV.
The photon deposits energy in the electromagnetic calo-rimeter in such a way that it is also reconstructed as a jet. Jets within R < 0:2 of the photon are therefore not con-sidered in this analysis. We require an angular separation Rð; jetÞ > 0:6 between the signal photon and all jets with pT>30 GeV to reduce the background from photons during fragmentation of final-state quarks (fragmentation photons) and to reduce the systematic effects from the leakage of nearby jet showers into the photon isolation energy measurement.
An additional reduction of the fragmentation photon background is achieved by requirements on the photon and jet pseudorapidities. Dijet production rates increase with jet pseudorapidity whereas rates for our assumed s-channel signal would diminish. We restrict the analysis to photons in the barrel calorimeter, jj < 1:37, and re-quire j jj < 1:4 between the photon and jet. The
former criterion was chosen to avoid kinematic bias of the mj distribution due to the inclusion of any range where reconstruction efficiency is lower, such as the barrel-endcap transition region1:37 < jj < 1:52. The latter was chosen by optimizing the expected significance using the j jj distributions found in excited-quark signal
simulation and background-dominated control data se-lected as in the nominal analysis but inverting the photon isolation requirement. This control sample is also used to check the background estimate.
After the above selections, Fig.1shows the distribution of the mj invariant mass in bins equal to the mass reso-lution. The mj resolution is about 4% at 600 GeV,
im-proving to 3% at 2 TeV. We determine the combined SM and instrumental background to the search by fitting this distribution to the four-parameter ansatz,
fðx mj=pffiffiffisÞ ¼ p1ð1 xÞp2xp3p4lnx: (1)
The motivation for this function is discussed in Refs. [16,35–37]. The fit result is also shown in Fig. 1. The bottom panel of the figure shows the statistical signifi-cance of the difference between data and the fit in each bin [38]. With a negative log-likelihood test statistic, the p
value is 23%, indicating that the data distribution is compatible with Eq. (1). The functional form also de-scribes the leading-orderPYTHIAdirect photon prediction for comparable event statistics.
We search for statistical evidence of a resonance in this distribution using the BUMPHUNTER algorithm [39]. The algorithm operates on the binned mjdistribution, compar-ing the background estimate with the data in mass intervals of varying contiguous bin multiplicities across the entire distribution. For each interval in the scan, it computes the significance of any excess found. The algorithm identifies the interval 784–1212 GeV, indicated by the vertical lines in Fig. 1, as the single most discrepant interval. The significance of the outcome is evaluated using the en-semble of possible outcomes for the significance of any region in the distribution in the background-only hypothe-sis, obtained by repeating the analysis on pseudodata drawn from the background function. Before including systematic uncertainties, the probability (p value) of ob-serving a background fluctuation at least as significant as the above, including the trials factor, or ‘‘look-elsewhere’’ effect, is 20%. Inclusion of systematic uncertainties ren-ders the p value similarly large.
Lacking evidence of any signal, we exclude two types of photonþ jet signals: a generic signal with a Gaussian distribution and arbitrary production cross section, and the excited-quark model. We compute Bayesian limits at 95% credibility level (CL) using a prior probability density that is constant for positive values of the signal production
cross section and zero for unphysical, negative values, as described in Ref. [40]. We consider systematic uncertain-ties on the expected signal yield due to imperfect knowl-edge of the detector: the integrated luminosity (3.7%), trigger efficiencies (<0:5%), and signal photon identifica-tion efficiencies (2.0%). The last of these consists of iso-lation (0.4%), pile-up interactions (0.5%), conversions (1.2%), simulation mismodeling (1.3%), and the extrapo-lation of the photon identification efficiency to high pT (<0:3%). Uncertainties on the photon energy scale (0.5%–1.5%), jet energy scale (2%–4%), and jet energy resolution (5%–15%) contribute through their effects on the signal distribution. These systematic uncertainties are treated as marginalized Gaussian nuisance parameters in the limit calculation.
We also evaluate two systematic uncertainties on the background estimate. To account for the statistical uncer-tainties on the background fit parameters, we repeatedly fit the background function to pseudodata for each bin drawn from Poisson distributions. The mean of the Poisson distribution for a given bin corresponds to the number of entries actually observed in that bin in the data. We then take the variation in the fit predictions for a given bin, 0.5% of the background at low mass to almost 10% of the background at 2 TeV, as indicative of the systematic uncertainty. We treat this bin-by-bin uncertainty in the limit as fully correlated, using a single nuisance parameter that scales the entire background distribution.
While our function can describe the mjshape for direct photon production, as modeled in the PYTHIA direct photonþ jet simulation, the function need not remain a good description of the full distribution after including nonisolated and fragmentation photon events. For ex-ample, the function describes the next-to-leading-order prediction implemented in JETPHOX, which includes the fragmentation photon contributions, for some viable choices of theory parameters but not for others.
The second background systematic uncertainty accounts for any unmodeled features of fragmentation photon events in our isolated photon sample. We fit the background function to the mjdistribution in the control data selected with the inverted isolation requirement, then measure for each mjbin the magnitude of any deviation from the fit,
and assign the ratio of the deviation to the fit expectation as a parametrization bias systematic uncertainty. To extrapo-late this uncertainty to large mj where few control data
exist, we fit the tail mj>1 TeV with a two-degree polynomial.
Figure 2 shows the model-independent limits on the effective cross section, cross section times branching fraction B times acceptance A times efficiency , of a potential signal as a function of the central mass of each signal template. We take the signal line shape to be a Gaussian distribution with one of three widths, G=mG ¼ 5%, 7%, and 10% of the central mass of the

Gaussian. The limit weakens as the width increases and the peak becomes less distinct. For example, for a 1 TeV signal the limit for a width of 10% is 1.6 times the limit for a width of 5%.
The limit on the effective cross section in the excited-quark model is shown in Fig.3as a function of the qmass. Also shown are 1 and 2 uncertainty bands indicating the underlying distribution of possible limit outcomes in the background-only hypothesis. The solid
line indicates the prediction from thePYTHIAexcited-quark
implementation. We exclude such excited quarks with masses below 2.46 TeV at 95% CL, complementing the more stringent exclusion below 2.99 TeVon this specific q model in the dijet final state [22].
In conclusion, the photonþ jet mass distribution measured inffiffiffi 2:11 fb1 of pp collision data collected at
s p
¼ 7 TeV by the ATLAS Collaboration has been examined for narrow resonances. The observed distribu-tion extends up to masses of about 2 TeV. It is well described by a smooth function fitted to it and assumed to represent the SM expectation. No evidence for the production of resonances is found. We set limits at 95% CL on the Gaussian line shape and excited-quark signal using Bayesian statistics. The limits on Gaussian resonances, for example, exclude 2 TeV resonances with effective cross sections near 5 fb. We also exclude the excited-quark model in the photonþ jet final state for masses up to 2.46 TeV. The limits reported here on the resonant production of new particles in the photonþ jet final state are the most stringent limits set to date in this channel.
