Description
We apply the joint threshold and transverse momentum dependent (TMD)
factorization theorem to introduce new threshold-TMD distribution functions, including threshold-TMD parton distribution functions (PDFs) and fragmentation functions (FFs). We apply Soft-Collinear Effective Theory and renormalization group methods to perform QCD evolution for both threshold-TMD PDFs and FFs. We show the universality of threshold-TMD functions among three standard processes, i.e., the Drell-Yan production in pp collisions, semi-inclusive deep-inelastic scattering, and back-to-back two hadron production in e+e- collisions.
