Title: Pion structure from lattice QCD

Abstract:
I will discuss lattice calculations of the pion valence parton distribution function (PDF) in the framework of large momentum effective theory (LaMET). The calculations are performed at two small lattice spacings a=0.04fm and a=0.06fm and the valence pion mass of 300 MeV. In addition to the pion PDF I also present results on the PDF of the first radial excitation of the pion, pi(1300). Furthermore, I will discuss new lattice results on the pion form factor. The talk is based on recent papers:
