# Parton distribution function of nucleon

• Dr. Fei GAO

## Abstract

We compute the parton distribution functions (PDFs) of nucleon at hadron scale with an analytic model motivated by Dyson-Schwinger equation approaches, and then applied the DGLAP evolution to get glue and sea distribution at higher energy scale. We also proposed a mechanism of sea asymmetry in nucleon, through an additional $q/\bar{q}\rightarrow \pi$ process in DGLAP evolution.
