Description
Recent years have seen prominent progress in the first-principles calculation of transverse-momentum-dependent parton distributions (TMDs) from the so-called lattice TMDs, which are equal time correlators that include quasi-TMDs and those from the Lorentz-invariant approach. In this talk, I will show that the lattice TMDs and TMDs are related by a factorization formula which can be rigorously derived in QCD. As a corollary, there is no mixing between quark and gluon sectors, or quark of different flavors, in the matching for lattice TMDs, which implies that their lattice calculations can be much simpler than the collinear parton distributions. We also verify these results at one-loop in perturbation theory.
