Azimuthal decorrelations between the two central jets with the largest transverse momenta are sensitive to the dynamics of events with multiple jets. We present a measurement of the normalized differential cross section based on the full data set (RLdt ¼ 36 pb1) acquired by the ATLAS detector during the 2010pffiffiffis¼ 7 TeV proton-proton run of the LHC. The measured distributions include jets with transverse momenta up to 1.3 TeV, probing perturbative QCD in a high-energy regime.

The production of events containing high transverse-momentum (pT) jets is a key signature of quantum
chro-modynamic (QCD) interactions between partons in pp collisions at large center-of-mass energies (pffiffiffis). The Large Hadron Collider (LHC) opens a window into the dynamics of interactions with high-pffiffiffi T jets in a new energy regime of
s p
¼ 7 TeV. QCD predicts the decorrelation in the azimu-thal angle between the two most energetic jets,, as a function of the number of partons produced. Events with only two high-pT jets have small azimuthal decorrelations,
, while is evidence of events with several high-pT jets. QCD also describes the evolution of the shape
of the distribution, which narrows with increasing leading jet pT. Distributions in therefore test
perturba-tive QCD (pQCD) calculations for multiple jet production without requiring the measurement of additional jets. Furthermore, a detailed understanding of events with large azimuthal decorrelations is important to searches for new physical phenomena with dijet signatures, such as super-symmetric extensions to the standard model [1].
In this Letter, we present a measurement of dijet azimu-thal decorrelations with jet pT up to 1.3 TeV as measured
by the ATLAS detector, beyond the reach of previous colliders. The differential cross section ð1=Þðd=dÞ is based upon an integrated luminosity RLdt ¼ ð36 4Þ pb1 [2]. The distribution is normalized by
the inclusive dijet cross section , integrated over the same phase space. This construction minimizes experimental and theoretical uncertainties. Previous measurements of from the D0 [3] and CMS [4] Collaborations are extended here to higher jet pT values.
Jets are reconstructed using the anti-kt algorithm [5]
(implemented withFASTJET[6]) with radius R ¼ 0:6, and the jet four-momenta are constructed from a sum over its constituents, treating each as an ðE; ~pÞ four-vector with
zero mass. The anti-ktalgorithm is well motivated since it
is infrared safe to all orders, produces geometrically well-defined conelike jets, and is used for pQCD calculations (from partons), event generators (from stable particles), and the detector (from energy clusters [7]). The azimuthal decorrelation is defined as the absolute value of the difference in azimuthal angle between the jet with the highest pT in each event, pmaxT , and the jet with the
second-highest pT in the event. There are nine analysis
regions in pmaxT , where the lowest region is bounded by
pmaxT > 110 GeV and the highest region requires pmaxT >
800 GeV [7]. Only jets with pT> 100 GeV and jyj < 2:8,
where y is the jet rapidity [8], are considered. The two leading jets that define are required to satisfy jyj < 0:8, restricting the measurement to a central y region where the momentum fractions (x) of the interacting partons are roughly equal and the experimental acceptance for multijet production is increased. In this region where 0:02 & x & 0:14, the parton distribution function (PDF) uncertainties are typically 3% (at fixed factorization scale) [9]. The cross sections, measured over the range =2 and normalized independently for each analysis region, are compared with expectations from a pQCD calculation [10] that is next-to-leading order (NLO) in three-parton produc-tion. The perturbative prediction for the cross section is Oð4
sÞ, where sis the strong coupling constant.
The angular decorrelation is sensitive to multijet con-figurations such as those produced by event generators like
SHERPA[11], which matches higher-order tree-level pQCD diagrams with a dipole parton-shower model [12]. Samples for 2 ! 2 6 jet production are combined using an im-proved parton matching scheme [13]. Event generators such as PYTHIA[14] and HERWIG [15] use2 ! 2 leading order pQCD matrix elements matched with phenomeno-logical parton-cascade models to simulate higher-order QCD effects. Such models have been successful at repro-ducing other QCD processes measured by the ATLAS Collaboration [7,16].
The ATLAS detector [17,18] consists of an inner track-ing system surrounded by a thin superconducttrack-ing solenoid providing a 2 T magnetic field, electromagnetic and hadronic calorimeters, and a muon spectrometer based on

large superconducting toroids. Jet measurements depend most heavily on the calorimeters. The electromagnetic calorimeter is a lead liquid-argon (LAr) detector with an accordion geometry. Hadron calorimetry is based on two different detector technologies, with scintillator tiles or LAr as the active medium, and with either steel, copper, or tungsten as the absorber material. The pseudorapidity () [8] and segmentations of the calorimeters are suffi-ciently fine to ensure that angular resolution uncertainties are negligible compared to other sources of systematic uncertainty.
A hardware-based calorimeter jet trigger identified events of interest; the decision was further refined in soft-ware [17,18]. Events with at least one jet that satisfied a minimum transverse energy (ET) requirement were
re-corded for further analysis. The events in each pmaxT range are selected by a single trigger with a given ET threshold,
and the lower end of the range is chosen above the jet pTat
which that trigger is 100% efficient. Three sets of trig-gered events with different integrated luminosity are con-sidered: 2:3 pb1 for 110 < pmaxT 160 GeV, 9:6 pb1 for 160 < pmaxT 260 GeV, and 36 pb1 for pmaxT > 260 GeV [2]. Events are also required to have a recon-structed primary vertex within 15 cm in z of the center of the detector; each vertex had 5 associated tracks. The inputs to the anti-ktjet algorithm are clusters of calorimeter
cells seeded by cells with energy that is significantly above the measured noise [7]. Jets reconstructed in the detector, whether in data or theGEANT4-based simulation [19,20], are corrected for the effects of hadronic shower response and detector-material distributions using a pT- and
-dependent calibration [7] based on the detector simula-tion and validated with extensive test beam [18] and col-lision data [21] studies. Jets likely to have arisen from detector noise or cosmic rays are rejected [22].
The resulting distribution is shown in Fig.1for jets with pT> 100 GeV. There are 146 788 events in the data
sample, 85 of which have at least five jets with pT >
100 GeV. Also shown is thePYTHIAsample with MRST 2007LO PDF [23] and ATLAS MC09 underlying event tune [24], processed through the full detector simulation and normalized to the number of events in the data sample. Two- and three-jet production primarily populates the region 2=3 < < while smaller values of re-quire additional activity such as soft radiation or more jets in an event. Figure 1 illustrates that the decorrelation increases when a third high-pT jet is also required.
Events with additional high-pT jets widen the overall
distribution.
The measured differential distributions in data are corrected in a single step with a bin-by-bin unfolding method [7] to compensate for trigger and detector ineffi-ciencies and the effects of finite experimental resolutions. These correction factors, evaluated using the PYTHIA
sample, lie within 9% of unity. The leading sources of
systematic uncertainty on the normalized cross section are the jet energy scale calibration (2%–17%) [7], the bin-by-bin unfolding method (1%–19%), and the jet energy and position resolutions (0:5%–5%). The ranges in parentheses represent the magnitude of the uncertainties near and =2, respectively, and correspond to the analysis region with the smallest statistical uncertainty (160 < pmaxT 210 GeV). Multiple pp interactions in the same beam crossing that can increase the measured jet energy are included in the evaluation of the jet energy scale uncer-tainties (< 0:8% on the cross section for all analysis regions).
The normalized differential cross section is shown for each of the nine pmaxT analysis regions as a function of
in Fig. 2. As pmaxT increases, and the probability for the
emission of a hard third jet is reduced, the fraction of events near becomes larger. Overlaid on the data are the results from a NLO pQCD ½Oð4sÞ calculation,
NLOJET þþ[10] withFASTNLO[25] and using the MSTW
2008 PDF [9]. The factorization and renormalization scales are set to pmaxT and are varied independently up and down by a factor of 2 to determine the scale uncer-tainties. The scale uncertainties are larger between =2 < < 2=3 where the pQCD calculation is effectively leading order in four-parton production. The PDF uncer-tainties are treated as the envelope of the 68% C.L. un-certainties from MSTW 2008 [9], NNPDF 2.0 [26], and CTEQ 10 [27], and are combined with the uncertainties resulting from an svariation of0:004; the s
contribu-tions dominate. The calculation is corrected for nonpertur-bative effects due to hadronization and the underlying event [28]; the correction is smaller than 3%. The fixed-order calculation fails near ! where soft processes dominate and contributions from logarithmic terms are enhanced. Figure3displays the ratio of the cross section

with respect to the NLO calculation. In most regions, the theory is consistent with the data. However, the prediction in the range110 < pmaxT < 160 GeV is relatively low in the central region of where the scale uncertainties are small.
The data are also compared with predictions [29] from
SHERPA, PYTHIA, and HERWIG in Fig. 4. The leading-logarithmic approximations used in these event generators’ parton-shower models effectively regularize the diver-gence at ! ; all three provide a good description of the data in this region. In the region =2 < < 5=6, where multijet contributions are significant, this observ-able distinguishes between the three generators. SHERPA, which explicitly includes higher-order tree-level diagrams, performs well in most and pmaxT regions. Having phenomenological parameters that have been adjusted to previous ATLAS measurements,PYTHIA[28] andHERWIG
[24] also describe the data.

several event generators successfully describe the general characteristics of our measurements, including the increas-ing slope of the distribution with pmaxT and the shape near =2 where events with multiple jets make a considerable contribution. Our data, which include jets with pT values that significantly exceed earlier
measure-ments, explore QCD in a new kinematic region.
