Title: Dijet azimuthal decorrelations for Δφ _dijet < 2π/3 in perturbative QCD

Abstract

We point out an inconsistency in perturbative QCD predictions previously used for dijet azimuthal decorrelations for azimuthal angles of Δφ _dijet < 2π/3 between the two jets. We show how the inconsistency arises and how the calculations can be modified to provide more accurate results that exhibit a smaller scale dependence and give a better description of the data than the inconsistent results. We also explain how the quality of the predictions strongly depends on a perceivedly minor detail in the definition of the dijet phase space and give recommendations for future measurements.

Measurement of dijet azimuthal decorrelations in $p p$ collisions at $\sqrt{s} = 8 TeV$ with the ATLAS detector and determination of the strong coupling

Journal Article Aaboud, M. ; Aad, G. ; Abbott, B. ; ... - Physical Review. D.

Here, a measurement of the rapidity and transverse momentum dependence of dijet azimuthal decorrelations is presented, using the quantity R_ΔΦ. The quantity R_ΔΦ specifies the fraction of the inclusive dijet events in which the azimuthal opening angle of the two jets with the highest transverse momenta is less than a given value of the parameter Δ_Φmax. The quantity R_ΔΦ is measured in proton-proton collisions at √s = 8 TeV as a function of the dijet rapidity interval, the event total scalar transverse momentum, and Δ_Φmax. The measurement uses an event sample corresponding to an integrated luminosity of 20.2 fb^–1 collectedmore »« less

QCD resummation of dijet azimuthal decorrelations in pp and pA collisions

Journal Article Gao, Mei-Sen ; Kang, Zhong-Bo ; Shao, Ding Yu ; ... - Journal of High Energy Physics (Online)

We study the azimuthal angular decorrelations of dijet production in both proton-proton (pp) and proton-nucleus (pA) collisions. By utilizing soft-collinear effective theory, we establish the factorization and resummation formalism at the next-to-leading logarithmic accuracy for the azimuthal angular decorrelations in the back-to-back limit in pp collisions. We propose an approach where the nuclear modifications to dijet production in pA collisions are accounted for in the nuclear modified transverse momentum dependent parton distribution functions (nTMDPDFs), which contain both collinear and transverse dynamics. This approach naturally generalizes the well-established formalism related to the nuclear modified collinear parton distribution functions (nPDFs). We demonstratemore »« less

Measurement of dijet azimuthal decorrelation in pp collisions at $$\sqrt{s}=8\,\mathrm{TeV} $$

Journal Article Khachatryan, V. ; Sirunyan, A. M. ; Tumasyan, A. ; ... - European Physical Journal. C, Particles and Fields

A measurement of the decorrelation of azimuthal angles between the two jets with the largest transverse momenta is presented for seven regions of leading jet transverse momentum up to 2.2TeV. The analysis is based on the proton-proton collision data collected with the CMS experiment at a centre-of-mass energy of 8TeV corresponding to an integrated luminosity of 19.7fb-1. The dijet azimuthal decorrelation is caused by the radiation of additional jets and probes the dynamics of multijet production. The results are compared to fixed-order predictions of perturbative quantum chromodynamics (QCD), and to simulations using Monte Carlo event generators that include parton showers,more »« less

Inclusive jet cross-sections and dijet azimuthal decorrelations with D0

Conference Strohmer, Raimund ; /Munich U. - PoS HEP2005:051,2006

We present a preliminary measurement of the inclusive jet cross-sections based on an integrated luminosity of 378 pb{sup -1} acquired with the D0 detector between 2002 and 2004 at a center of mass energy of {radical}s = 1.96 TeV and a measurement of azimuthal dijet decorrelations based on an integrated luminosity of 150 pb{sup -1}. The cross section measurements are based on an iterative cone algorithm with a cone size of R = 0.7. They are performed in two rapidity bins between 0.0 and 0.8. The measurements are in good agreement with next to leading order calculations. The azimuthal anglemore »« less
