QCD factorization for spin-dependent cross sections in DIS and Drell–Yan processes at low transverse momentum

Built on a recent work on the quantum chromodynamic (QCD) factorization for semi-inclusive deep-inelastic scattering (DIS), we present a set of factorization formulas for the spin-dependent DIS and Drell–Yan cross sections at low transverse momentum. The result can be used to extract transverse-mome...

Description
Summary:Built on a recent work on the quantum chromodynamic (QCD) factorization for semi-inclusive deep-inelastic scattering (DIS), we present a set of factorization formulas for the spin-dependent DIS and Drell–Yan cross sections at low transverse momentum. The result can be used to extract transverse-momentum dependent parton distribution and fragmentation functions from relevant experimental data.
