Published 15 Jan 2020 in hep-ph, astro-ph.HE, hep-lat, and nucl-th | (2001.05327v1)
Abstract: We derive the axion-nucleon interaction Lagrangian in heavy baryon chiral perturbation theory up to next-to-next-to-leading order. The effective axion-nucleon coupling is calculated to a few percent accuracy.
