Axions in Baryon Chiral Perturbation Theory
arXiv:2201.08132 · doi:10.22323/1.412.0019
Abstract
I give an overview of recent developments in the study of the coupling of the QCD axion to nucleons and other octet baryons. I demonstrate how axions can be included into heavy baryon chiral perturbation theory, and present recent numerical results for the several axion-baryon couplings in SU(2) and SU(3) chiral perturbation theory for the Kim--Shifman--Vainstein--Zakharov (KSVZ) and the Dine--Fischler--Srednicki--Zhitnitsky (DFSZ) axion model.
