The CKM phase and θ ¯ $$ \overline{\theta} $$ in Nelson-Barr models
Abstract We analyze the Nelson-Barr approach to the Strong CP Problem. We derive the necessary conditions in order to simultaneously reproduce the CKM phase and the quark masses. Then we quantify the irreducible contributions to the QCD topological angle, namely the corrections arising from loops of...
