Abstract

We briefly review the question of spontaneous CP violation in some models of weak interactions. The next-to-minimal supersymmetric standard model, with two Higgs doublets and one gauge singlet, is one of the minimal extensions of the standard model where SCPV is viable. We analyse the possibility of spontaneous CP violation in the next-to-minimal supersymmetric standard model with an extra singlet tadpole term in the scalar potential, and confirm the existence of phenomenologically consistent minima with non-trivial CP violating phases.
