| Publication Abstract: | The Drell-Yan hadronic tensor for electromagnetic (EM) current in the Sudakov region s?Q2?q2? is obtained
with 1Q2 accuracy.
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.
