Parton distribution functions on the lattice


X. Feng (PKU) / F. Steffens (UB)


Using lattice QCD and the recently developed large-momentum effective theory (LaMET), this
project aims at studying various aspects of the partonic structure of the nucleon. In particular, these
are the computation and the understanding of the physical mechanism behind the flavour
asymmetry in the nucleon, the investigation of the reliability of computing the gluon distribution
using LaMET, and the first calculation of the nucleon generalized parton distributions (GPDs) on
the lattice at the physical pion mass.
