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 $$ s\gg {Q}^2\gg {q}_{\perp}^2 $$ with 1 Q 2 $$ \frac{1}{Q^2} $$ accuracy, first at the tree level and then with the double-log accuracy. It is demonstrated that in the leading...
