The chiral Lagrangian of CP-violating axion-like particles

Abstract We discuss the construction of the most general CP-violating chiral Lagrangian for an axion-like particle (ALP). Starting with an effective Lagrangian containing light quarks and gluons, we provide its matching onto a chiral effective Lagrangian at O $$ \mathcal{O} $$ (p 2) described in ter...
