Description
We present a lattice determination of pion valence parton distribution function (PDF) and electomagnetic form-factors. Our study use NNLO leading-twist perturbative matching formula to extract first few moments and reconstruct the x-dependent PDF of pion. Three mixed action ensambles including a physical pion mass with fine lattice spacings of a = 0.04, 0.06 and 0.076 fm are used to investigate the mass dependence as well as approaching continuum limit.
