The and other open-charm states in relativistic chiral effective field theory
Ze-Rui Liang, Qi-Chao Xiao, Zhi-Hui Guo +1
We derive the pertinent chiral potentials for charmed vector meson interactions with light pseudoscalar bosons in a relativistic U(3) chiral effective field theory up to next-to-le…
Prominent enhancement of axion thermalization rate from axion-kaon interactions
Jin-Bao Wang, Zhi-Hui Guo, Hai-Qing Zhou
The axion thermalization rate is a crucial input to determine the hot dark matter bound of axions, resulting from the scattering processes in the thermal bath of early Universe. We…
Isospin-breaking contribution to the model-independent axion-photon-photon coupling in chiral theory
Rui Gao, Jin Hao, Chun-Gui Duan +3
We pursue the calculation of the model-independent component of the axion-photon-photon coupling in the chiral perturbation theory up to next-to-leading order, with the emph…
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 production in the decay within chiral perturbation theory
Jin-Bao Wang, Zhi-Hui Guo, Zhun Lu +1
We study the axion and axion-like particle production from the decay within the chiral perturbation theory up to the one-loop level. The conventional c…
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…
