Spontaneous CP Phases and Flavour Changing Neutral Currents in the Left-Right Symmetric Model

We study the behaviour of the flavour changing neutral currents in the Left-Right Symmetric Model related to the presence of spontaneous CP phases. To do this, we explore four cases corresponding to combinations of maximal and no CP violation in both the lepton and quark sector. We find that we can constrain the flavour changing neutral currents to the experimental limit, by adjusting the CP-violating phase of the quark sector, opening the possibility to obtain a large CP violation in the lepton sector as well as new Higgs bosons at the electroweak scale.
