Comprehensive study of axion photoproduction off the nucleon in chiral effective field theory
Xiong-Hui Cao, Zhi-Hui Guo
We calculate the amplitudes of the axion photoproduction off the nucleon, i.e., , within the framework of chiral effective field theory. Several different types of con…

Axion-like particle production from lepton-nucleon scattering in chiral effective theory
Qian-Qian Guo, Xiong-Hui Cao, Zhi-Hui Guo +1
In this work we study the axion/axion-like particle production from the lepton-nucleon scattering in the low-energy region, i.e., the processes, being t…

Double pion photoproduction off nucleons in covariant chiral perturbation theory
Kai-Ge Kang, Xiong-Hui Cao, De-Liang Yao +1
The double pion photoproduction off nucleons near threshold is analyzed in a covariant baryon chiral perturbation theory up to next to leading order, where the , $N^*(140…
