      abstract     = {In the past, the axion-nucleon coupling has been calculated
                      in the framework of SU(2) heavy baryon chiral perturbation
                      theory up to third order in the chiral power counting. Here,
                      we extend these earlier studies to the case of heavy baryon
                      chiral perturbation theory with SU(3) flavor symmetry and
                      derive the axion coupling to the full SU(3) baryon octet,
                      showing that the axion also significantly couples to
                      hyperons. As studies on dense nuclear matter suggest the
                      possible existence of hyperons in stellar objects such as
                      neutron stars, our results should have phenomenological
                      implications related to the so-called axion window.},
