Recent Parton-Distribution Results from Lattice QCD at Physical Pion Mass
ORAL
Abstract
There have been rapid developments in the direct calculation of the Bjorken-x dependence of parton distribution functions (PDFs) using lattice QCD. Among various new methods, large-momentum effective theory (LaMET), which calculates boosted hadron matrix elements at multiple spatial displacements on the lattice, shows promising PDFs. In this talk, I will report a few recent results on pion PDFs and nucleon generalized parton distributions (GPDs) calculated directly at the physical pion mass.
