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.

Heavy Quark Limit

As heavy baryon ΛQ (Q=b or c) consists of a heavy quark and a scalar light diquark, we establish the Bethe-Salpeter (B-S) equation for ΛQ in the heavy quark limit. With the reasonable kernel we solve the B-S equation numerically and calculate the Isgur-Wise function as Λb→Λc.
