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…
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…
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…
In-depth Study of Spin- and Momentum-Dependent Interaction Potentials Between Two Spin-1/2 Fermions Mediated by Light Spin-0 Particles
Yang Zhong, Zhi-Hui Guo, Hai-Qing Zhou
We present a calculation by including the relativistic and off-shell contributions to the interaction potentials between two spin-1/2 fermions mediated by the exchange of light spi…
