G. Barenboim et J. Bernabeu, SPONTANEOUS BREAKDOWN OF CP IN LEFT-RIGHT-SYMMETRICAL MODELS, Zeitschrift fur Physik. C, Particles and fields, 73(2), 1997, pp. 321-331
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.
