Description

We adopt a chiral nucleon-pion Lagrangian and formulate a Basis Light-Front Quantization approach to solve the resulting light-front Hamiltonian of a nucleon as an eigenvalue problem. We obtain the nucleon mass spectrum and the corresponding light-front wave functions. Based on the light-front wave functions, we calculate the parton distribution functions as well as the elastic electromagnetic form factors of the nucleon. In this talk, we will present the current progress of our research and discuss the prospects for further applications.
