  We present detailed analysis of the $T$-even lepton angular distribution in
the Drell-Yan process including $\gamma/Z^0$ gauge boson exchange and using
perturbative QCD based on the collinear factorization scheme at leading order
in the $\alpha_s$ 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.
