Axions in Baryon Chiral Perturbation Theory

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...

Sumario: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.
