Abstract

We present a lattice QCD calculation of transverse momentum dependent parton distribution functions (TMDs) of protons using staple-shapedWilson lines. For time-reversal odd observables, we calculate the generalized Sivers and Boer-Mulders transverse momentum shifts in SIDIS and DY cases, and for T-even observables we calculate the transversity related to the tensor charge and the generalized worm-gear shift. The calculation is done on two different n_f = 2+1 ensembles: domain-wall fermion (DWF) with lattice spacing 0:084fm and pION mass of 297MeV, and clover fermion with lattice spacing 0:114fm and pION mass of 317MeV. The results from those two different discretizations are consistent with each other.
