Parton distribution inside the pion from lattice QCD
ORAL · Invited
Abstract
We will present our lattice computation of the valence Parton Distribution Function of 300 MeV pion. For this work, we use perturbative matching of the Euclidean RI-MOM renormalized quasi Parton Distribution Function that we compute on HISQ ensembles with 0.06 and 0.04 fm lattice spacings. In addition, we will discuss the validity of leading order perturbative matching and other systematic effects that potentially enter such lattice computations of PDF.
