SPONTANEOUS BREAKDOWN OF CP IN LEFT-RIGHT-SYMMETRICAL MODELS

We show that it is possible to obtain spontaneous CP violation in the minimal SU(2)(L) x SU(2)(R) x U(1)(B - L), i.e. in a left right symmet ric model containing a bidoublet and two triplets in the scalar sector . For this to be a natural scenario, the non-diagonal quartic coupling s between the two scalar triplets and the bidoublet play a fundamental role. We analyze the corresponding Higgs spectrum, the suppression of FCNC's and the manifestation of the spontaneous CP phase in the elect ric dipole moment of the electron.
