CP-VIOLATING PARAMETERS IN A LEFT–RIGHT SYMMETRIC MODEL WITH AN ${\rm SU}(3)^{VL}_H$ HORIZONTAL SYMMETRY

Abstract

CP-violation can occur in the horizontal gauge boson sector of an [Formula: see text] gauge model with natural flavor conservation (NFC) in the scalar sector. We perform explicit calculations in the model of the CP-violating parameters ε and ε′/ε in the neutral kaon sector and of the electric dipole moment of the neutron (dn), along with the usual neutral meson mixings. For the full range of parameter space where the model is consistent with current experimental data on ε, one obtains very small values for the parameters ε′/ε and dn.
