Description
We present detailed analysis of the T-even and T-odd lepton angular distribution in the Drell-Yan
process including γ/Zˆ0 gauge boson exchange and using perturbative QCD based on the collinear
factorization scheme at leading order in the α_s expansion and α_sˆ2 for T-odd . We focus on the
study of the transverse momentum Q_T dependence of the corresponding hadronic structure functions and angular coefficients up to next-to-next-to-leading order in the Q_Tˆ2/Qˆ2 expansion. We
analyze Q_T dependence numerically and compare T-even angular coefficients with available data
of the ATLAS Collaboration at LHC.
