Light-cone singularities and transverse-momentum-dependent factorization at twist-3
We study transverse-momentum-dependent factorization at twist-3 for Drell–Yan processes. The factorization can be derived straightforwardly at leading order of αs. But at this order we find that light-cone singularities already exist and effects of soft gluons are not correctly factorized. We regula...
