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 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…
