Description
Recent researches showed that the light-cone parton distributions can be accessed by investigating the quasi distributions which are space-like correlation functions, hence can be directly simulated on the lattice. In this talk, I will show the one-loop matching between the light-cone and quasi PDFs, GPDs. The matching condition is essential to extract the light-cone distribution from the quasi distributions. I will also discuss the light-cone and quasi heavy meson distribution amplitude which is perturbatively calculable through NRQCD refactorization.
