Valence Structure of Pion from Lattice QCD: Physical Mass, Chiral Quarks

We study pion valence structure from lattice QCD using three mixed action ensambles including a physical pion mass with fine lattice spacings of a $=$ 0.04, 0.06 and 0.076 fm. Our analysis use ratio-based schemes to renormalize the equal-time bilocal quark-bilinear matrix elements. We extract first few moments and reconstruct the x-dependent PDF using NNLO leading-twist perturbative matching formula, and investigate the mass dependence as well as approaching continuum limit. Two Domain-Wall ensambles are used to cross check our estimate.
