Flavor constraints for a vector-like quark of Nelson-Barr type
Abstract The Nelson-Barr (NB) mechanism to solve the strong CP problem assumes CP conservation, arranges vanishing θ ¯ $$ \overline{\theta} $$ at tree-level and requires vector-like quarks (VLQs) to transmit the CP breaking to the SM. We analyze the flavor constraints coming from the presence of one...
