We present comprehensive analysis of the angular structure of the Drell-Yan process at different rapidity and kinematical ranges using data of the ATLAS, LHCb, and CMS Collaborations at CERN LHC. From theory side we discuss next-to-leading order calculations in the framework of the collinear perturbative QCD and geometrical method.
We present detailed analysis of the $T$-even lepton angular distribution in the Drell-Yan process including $γ/Z^0$ gauge boson exchange and using perturbative QCD based on the collinear factorization scheme at leading order in the $α_s$ expansion. We focus on the study of the transverse momentum $Q_T$ dependence of the corresponding hadronic structure functions and angular coefficients up to next-next-to-leading order in the $Q_T^2/Q^2$ expansion. We analyze $Q_T$ dependence numerically and compare $T$-even angular coefficients integrated over rapidity with available data of the ATLAS Collaboration at LHC. Additionally, we present our results for the forward-backward asymmetry and compare it with data.
