Studies of low energy $l + p \to l + p + γ$ process in covariant chiral perturbation theory

Xu Wang, Kai-Ge Kang, Zhiguang Xiao +1

This study presents a tree-level calculation of the scattering amplitude for the $l p \to l p γ$ (with a hard photon) process within the framework of Chiral Perturbation Theory. Our ca…

Studies on quark-mass dependence of the $N^{*} (920)$ pole from $π N$ $χ$ PT amplitudes

Xu Wang, Kai-Ge Kang, Qu-Zhi Li +2

The quark-mass dependence of the $N^{*} (920)$ pole is analyzed using $K$ -matrix method, with the $π N$ scattering amplitude calculated up to $O (p^{3})$ order in chiral perturbation theo…
