| Title | Gauge-invariant TMD factorization for Drell-Yan hadronic tensor at small $x$ | ||||
| Abstract | The Drell-Yan hadronic tensor for electromagnetic (EM) current is calculated in the Sudakov region s >>? Q^2 >>? q^2 with 1/Q^2 accuracy, first at the tree level and then with double-log accuracy. It is demonstrated that in the leading order in N_c 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 h1 . The order-of-magnitude estimates of angular distributions for DY process seem to agree with LHC results at corresponding kinematics. | ||||
