Description
Non-perturbative parton distributions that arise in the factorization of cross-sections are inaccessible to direct lattice QCD calculations, as their lightcone-dominated dynamics induce a real-time sign problem. One may circumvent this issue by constructing a lattice-calculable distribution that shares the same IR physics as the desired physical distribution, and then connecting the two distributions with a factorization formula. In this talk, I prove such a relation for quasi (lattice) and Collins (physical) TMDs that holds at leading power to all orders in α_s, for all spins and parton flavors.
