Abstract: The Drell-Yan hadronic tensor for electromagnetic (EM) current is calculated in the Sudakov region s»Q2»q2⊥ with 1Q2 accuracy, first at the tree level and then with the double-log accuracy. It is demonstrated that in the leading order in Nc the higher-twist quark-quark-gluon TMDs reduce to leading-twist TMDs due to QCD equation of motion. The resulting tensor for unpolarized hadrons is EM gauge-invariant and depends on two leading-twist TMDs: f1 responsible for total DY cross section, and Boer-Mulders function h⊥1. The order-of-magnitude estimates of angular distributions for DY process seem to agree with LHC results at corresponding kinematics.
