Transverse momentum dependent distribution functions in the threshold limit
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 renormalizati...

Summary: | 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 carry out 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. In the end, we present the numerical predictions for different threshold-TMD functions and also transverse momentum distributions at \(pp\), \(ep\), and \(e^+e^-\) collisions. |
