The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the Large Hadron Collider using the CMS experiment. The data sample corresponds to an integrated luminosity of34 pb1. The measurement is made for jet transverse momenta in the range 18–1100 GeVand for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pTever observed
and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.

The measurement of the inclusive jet cross section is a benchmark of the standard model (SM) at hadron colliders [1,2]. At the Large Hadron Collider (LHC), jets produced in the high center-of-mass energy collisions test the SM at the smallest distance scales presently possible can con-strain parton momentum distributions in the proton and are sensitive to the strong coupling constant. Significant deviations from predictions of the inclusive jet cross sec-tion at high transverse momentum pT could also be an
indication of new phenomena beyond the SM. Results from the Tevatron p p collider demonstrate agreement with next-to-leading-order (NLO) theoretical predictions from per-turbative quantum chromodynamics (pQCD) for jets in the approximate pT range of 50–700 GeV, using about1 fb1
of data at a center-of-mass energypffiffiffis¼ 1:96 TeV [3–5]. Early results from the ATLAS Collaboration for jets in the pT range 60–600 GeV, based on a17 pb1data sample of
pp collisions atpffiffiffis¼ 7 TeV at the LHC [6], also indicate agreement with theoretical predictions. Using a data sam-ple corresponding to 34 pb1 of integrated luminosity from pp collisions recorded by the CMS detector at the LHC with pffiffiffis¼ 7 TeV, we significantly extend the pT
range from previous measurements of the inclusive jet pT spectrum to 18–1100 GeV and for rapiditiesjyj < 3:0.
The rapidity y is defined as y ¼12 ln½ðE þ pzÞ=ðE pzÞ,
where E is the jet energy and pzis the component of the
jet momentum along the beam axis. The inclusive jet cross section is defined as d2jet=ðdpTdyÞ ¼ Njet=
ðpTyÞ½1=ðLÞ, where Njet is the number of jets per
bin,pT andy are the bin widths in pT and y, L is the total integrated luminosity, and is the product of event and jet selection efficiencies. All jets with pT> 18 GeV in
a proton-proton collision event are used in the
measure-ment. In this Letter, the inclusive jet cross section is compared with theoretical predictions at NLO in pQCD.
The CMS detector has silicon pixel and microstrip trackers covering pseudorapidities up tojj ¼ 2:5, where ¼ ln½tanð=2Þ and is the polar angle relative to the counterclockwise proton beam direction. Together with a 3.8 T solenoid, the trackers enable track reconstruction down to transverse momenta of about 100 MeV and a resolution of about 1% at 100 GeV. A high-granularity electromagnetic crystal calorimeter (ECAL) extends up to jj ¼ 3:0 and has an energy resolution of better than 0.5% for unconverted photons with transverse energies above 100 GeV. A hermetic hadronic calorimeter (HCAL) extends up to jj ¼ 5:0 with a transverse had-ronic energy resolution of about100%= ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiET½GeV

5%. The calorimeter components relevant to this work may be described in terms of a cylindrical barrel region, extending up to jj ¼ 1:5, and two end caps, covering 1:5 < jj < 3:0. An efficient muon system is used to reconstruct and identify muons up tojj ¼ 2:4. Events are collected using a two-level trigger system, consisting of a hardware level-1 and a software high level trigger. Jets formed online by the trigger system use the energies measured in the ECAL and HCAL and are uncorrected for the jet energy response of the calorimeters. This study uses inclusive single-jet trig-gers corresponding to pT thresholds of 6, 15, 30, 50, 70,
100, and 140 GeV. Finally, a minimum-bias trigger is defined as a signal from at least one of two beam scintilla-tor counters in coincidence with a signal from one of two beam pickup timing devices. The CMS coordinate system is right handed, with the origin centered at the nominal collision point, the x axis pointing radially toward the center of the LHC, the y axis pointing vertically upward, and the z axis pointing along the beam direction. More details about the CMS detector can be found in Ref. [7].
This measurement uses the infrared- and collinear-safe anti-kT jet algorithm [8] as implemented in Ref. [9]. The
algorithm is a sequential clustering algorithm similar to the well-known kT algorithm [10,11] except that it uses1=p2T
instead of p2T as the weighting factor for the scaled *Full author list given at the end of the article.

distance. The algorithm produces jets that are cone shaped in the rapidity-azimuth plane, except when jets overlap. The CMS particle-flow (PF) algorithm reconstructs indi-vidual particles (leptons, photons, charged and neutral hadrons) by linking tracks, ECAL clusters, and HCAL clusters. The momentum or energy of each particle is measured based on information from all subdetectors. Broadly speaking, electrons are reconstructed from tracks and calibrated ECAL clusters; muons are reconstructed using tracks; charged hadrons are reconstructed from tracks and calibrated ECAL and HCAL clusters; photons and neutral hadrons are reconstructed from calibrated ECAL and HCAL clusters, respectively. A detailed de-scription of the PF algorithm and performance can be found in Ref. [12] and references therein. Jets are recon-structed by clustering particles, including leptons. Because the energy response of each reconstructed particle is close to unity, the jet momentum response is also close to unity and only small corrections (at the level of 5%–10%) are needed [13,14]. The bulk of these corrections are derived from simulation [15] with residual corrections determined from data. First, using an exclusive dijet sample containing back-to-back jets in azimuth, a residual relative correction of up to 8% removes any remaining pseudorapidity depen-dence of the jet momentum response. Second, using an exclusive data sample containing a single hadronic jet recoiling back to back in azimuth against a well measured photon [14], a small residual absolute correction of about 1% restores the response to unity. Jet momenta are further corrected for the pileup of multiple proton-proton colli-sions [16], which ranged from nearly zero additional colli-sions at the very early period of LHC data taken in 2010 to an average of about three near the end of the 2010 running period. Finally, the jet momentum resolution is determined as a function of the jet pT and y from simulation.
Comparing the pT balance in dijet events between data
and simulation, the jet pT resolution from simulation is
scaled to be about 10% larger in the barrel and about 20% larger in the end caps to match that from data [13,14].
The efficiency of a given inclusive single-jet trigger is determined as the ratio of its trigger rate to either the minimum-bias trigger rate or the rate of the lower-pT
trigger preceding it. The minimum jet pT is chosen so
that the trigger efficiency exceeds 99% for each data set. All events are required to have a primary vertex (PV) satisfying the following selection: the fit for the PV must include at least three associated tracks, the PV must lie within 0.15 cm of the beam axis, and the z coordinate of the PV must lie within the luminous collision regionjzPVj < 24 cm. This selection rejects noncollision and beam-related backgrounds. Loose jet identification criteria [17] are applied requiring that each jet within the tracker’s fiducial acceptance have at least two particles, of which at least one must be a charged hadron. Further, at most 90% of the jet energy is allowed to be from photons or neutral
hadrons. Beyond the tracker acceptance, each jet is re-quired to have both electromagnetic and hadronic energy. To remove effects from anomalous calorimeter noise, beam halo, or cosmic-ray backgrounds, events are rejected if the missing transverse momentum is both larger than 50% of the total visible transverse energy and larger than 100 GeV. The missing transverse momentum is defined as the modulus of the negative transverse vector sum over the momenta of all reconstructed particles in the event. Any inefficiency in selecting jets, due to the above criteria, is estimated from simulation to be negligible.
Because of resolution effects, a jet may fall into a differ-ent pT bin than the one corresponding to the true
under-lying, hadron-level jet. Such bin-to-bin migrations distort the rapidly falling pT spectrum. Each pT bin width is
chosen to be larger than the reconstructed jet pTresolution
in the bin to minimize the migration effects and large enough to ensure that statistical fluctuations do not domi-nate the measurement. The jet pTspectra are corrected for
resolution effects where the true jet pT spectrum is
mod-eled by a power-law ansatz motivated by the parton model, modified by a kinematic cutoff term at high pT:
fðpT; ; ; Þ ¼ N0½pT½1 p1ffiffis2pT coshðyminÞ
exp½=pT, where N0 is a normalization factor, ; ;
are fit parameters, and ymin is the low-edge of the rapidity
bin y under consideration. Similar parametrizations have been previously used by other experiments [5,6,18]. The function is then smeared using the jet pTresolutions in bins
of pT and y. The parameters of the model are extracted by
fitting the smeared transverse momentum spectrum to the experimental data. The data points are placed at the bin center, defined as the point where the value of the predicted function is equal to its mean value over the bin width. The pT resolution corrections for each bin in pT and y,
deter-mined by taking the ratio of the function to the smeared function, range from 5% to 10% as a function of pTin the
central rapidity bin and range from about 10% to 50% in the most-forward rapidity bin. Jet migrations across y bins due to y resolution are found to be negligible within the tracker’s fiducial acceptance. Using simulation, migrations of up to 5% are observed and corrected across bins whose boundaries lie near the tracker acceptance.
The primary sources of systematic uncertainties in the cross section measurement arise from the jet momentum scale and resolution, as well as the integrated luminosity. The jet transverse momentum scale is sensitive to several effects including (a) the photon energy scale (known to 1.0% [19] and used to derive the residual absolute response corrections), (b) the relative response across detector re-gions (known to within 2.6% [14]), (c) pile-up effects (known to within 0.2% for very low pile-up conditions with low-pT jet triggers or for intermediate pile-up
con-ditions with high-pT jet triggers), and (d) the calibration
extrapolation to transverse momenta above available photon energies (dominated by uncertainties in jet
fragmentation and estimated to be within 4% at 1100 GeV [14]). With those considerations, the total uncertainty in the jet transverse momentum scale is determined to be between 3% and 4% in the ranges18 < pT< 1100 GeV andjj < 3:0. The jet momentum resolutions for different y bins are known to within 10% at jyj < 1:5, increasing to 15% for1:5 < jyj < 2:0, 25% for 2:0 < jyj < 2:5, and 30% for2:5 < jyj < 3:0 [13]. The integrated luminosity of the proton-proton collisions is known with a precision of 4% [20] and directly translates into a 4% normalization uncer-tainty on the inclusive jet cross section.
The next-to-leading-order perturbative QCD theoretical predictions are derived usingNLOJET++2.0.1 [21,22] within the framework ofFASTNLO 1.4 [23]. Other NLO calcula-tions are available in Refs. [24–26]. TheFASTNLO frame-work is used for propagating uncertainties due to different parton distribution function (PDF) sets, s values, and
scale choices. Nonperturbative (NP) corrections for hadro-nization and multiple parton interactions are estimated usingPYTHIA6.422 [27] and HERWIG++2.4.2 [28], which are applied to the NLO pQCD prediction. The correction is defined as the average of the models, and the associated theoretical uncertainty is assumed to be half of the differ-ence between the two predictions. For low-pTjets, the NP
correction can be as large as 30%, with a relative uncer-tainty of 100%. Uncertainties from any residual depen-dence on the choice of renormalization scale r and
factorization scale fare determined by varying the scales
according to the following combinations [29]:ð12r;12fÞ,
ð1
2r; fÞ, ðr;12fÞ, ðr; 2fÞ, ð2r; fÞ, and ð2r;
2fÞ. The default choice is r¼ f¼ pT. These scale
variations modify the prediction of the inclusive jet cross section by about 5%–10%. Following the PDF4LHC Working Group recommendation [30], PDF uncertainties are evaluated via a prescribed envelope, defined as the maximum variation between different NLO PDF sets con-structed from CT10 [31], MSTW2008NLO [32], and NNPDF2.0 [33], including their respective uncertainties and using their respective default values of the strong coupling constant sðmZÞ ¼ 0:1180, 0.1190, and 0.1202.
The middle of the envelope is taken as the central predic-tion. The uncertainties are on the order of 10% up to a pT
of 800 GeV, except when approaching the kinematic limit where they can be as large as 40%. More detailed com-parisons with individual NLO PDF sets are reported sepa-rately in Ref. [34]. Finally, an additional uncertainty from the current knowledge of the strong coupling constant is calculated from the CT10as PDF set [31] with values of sðmZÞ varied conservatively by 0:002 and added in
quadrature to the PDF uncertainty. The uncertainties due to these variations in sðmZÞ are between 2.5% and 5.0%.
The PDF uncertainties are dominated by differences be-tween PDF sets in the PDF4LHC recommendation for 50 < pT < 500 GeV, and by uncertainties within a single
PDF set for pT> 500 GeV.
The fully corrected inclusive jet cross section is shown in Figs.1and2. Figure1shows the jet pTspectra between
18 and 1100 GeV, falling over 10 orders of magnitude in rate, and for six different rapidity bins. The comparison with the theoretical NLO prediction, corrected for NP effects, is more easily discerned in Fig.2, which provides the ratio of the jet pT spectra from data to the theoretical
prediction for each of the six rapidity bins. The total theoretical systematic uncertainty from the prediction is superimposed as solid lines above and below unity, and the total systematic uncertainty due to experimental effects is centered on the data points as a shaded band. The central predictions for the CT10, MSTW2008NLO, and NNPDF2.0 PDF sets are also overlayed. The PDF uncer-tainties are large and asymmetric at high jet pT,
dominat-ing the theoretical uncertainty band. Nevertheless, compared to the PDF4LHC recommendation, similar trends between data and the central prediction of each PDF set are observed. Within the experimental and theo-retical uncertainties, the predictions are seen to be consis-tent with the data across a wide range of jet pT and
rapidities, although the predictions are systematically above the data.
In conclusion, using a data sample corresponding to 34 pb1 of integrated luminosity from pp collisions
re-corded by the CMS detector at the LHC with a center-of-mass energy of 7 TeV, the jet transverse momentum spec-trum has been measured for18 < pT< 1100 GeV and for six rapidity bins up tojyj ¼ 3:0. The dominant systematic uncertainties arise from the absolute jet momentum scale and resolution, as well as the integrated luminosity

measurement. The NLO pQCD predictions for the inclu-sive jet cross section, corrected for nonperturbative effects and using the PDF4LHC recommendations, are generally in agreement with the data. This measurement extends to the highest values of jet pT ever observed.
