Baryon mass splittings and strong CP violation in SU(3) Chiral Perturbation Theory

Jordy de Vries, Emanuele Mereghetti, Andre Walker-Loud

We study $SU(3)$ flavor-breaking corrections to the relation between the octet baryon masses and the nucleon-meson CP-violating interactions induced by the QCD $\bar{\theta }$ term. We wor…
