CP-violating Phenomena in an $SU(2{)}_L\times SU(2{)}_R\times U(1{)}_{B-L}\times SU(3{)}_H^{VL}$ Horizontal Symmetric Model

Abstract

We consider an $SU(2{)}_L\times SU(2{)}_R\times U(1{)}_{B-L}\times SU(3{)}_H^{VL}$ gauge model with natural flavour conservation in the Higgs sector, in which CP-violation occurs due to the horizontal interactions only. We calculate the CP-violating observables $\hat{I}\mu$ and $\hat{I}{\mu }^{\prime }$ of the neutral kaon sector and $d_n$, the electric dipole moment of the neutron. The regions of the parameter space which yield a value of $\hat{I}\mu$ that is in agreement with the experiment, lead to predictions for $\hat{I}{\mu }^{\prime }$ and $d_n$ which are at least five orders of magnitude smaller than the current experimental upper bounds.
