One-Loop Corrections of Single Spin Asymmetries in Semi-Inclusive DIS
A. P. Chen, J. P. Ma, G. P. Zhang
We study single spin asymmetries at one-loop accuracy in semi-inclusive DIS with a transversely polarized hadron in the initial state. Two measurable spin observables are predicted…

Light-Cone Singularities and Transverse-Momentum-Dependent Factorization at Twist-3
A. P. Chen, J. P. Ma
We study transverse-momentum-dependent factorization at twist-3 for Drell-Yan processes. The factorization can be derived straightforwardly at leading order of . But at this o…

One-Loop Corrections of Single Spin Asymmetries at Twist-3 in Drell-Yan Processes
A. P. Chen, J. P. Ma, G. P. Zhang
We study single spin asymmetries at one-loop accuracy in Drell-Yan processes in which one of the initial hadrons is transversely polarized. The spin-dependent part of differential…
