Title: Some recent progress in LaMET


Abstract:

Parton distribution functions (PDFs) are mandatory inputs in high energy scattering and also play an important role in searching for new physics at high energy. The recently proposed large momentum effective theory (LaMET) allows one to access the PDFs from first principle Lattice QCD. In this talk, I will review the recent progress on quasi-PDFs, in particular on the lattice QCD stimulation of soft function and the perturbative calculation at two-loop.
