Constraints on a model with pure right-handed third generation couplings -art. no. 055007

We examine constraints on a model with pure right-handed third generation c harged couplings. The parameters of the right-handed mixing matrix and the right-handed coupling strength are constrained from semileptonic B decays, the mass difference of neutral mesons, the CP violating observables epsilon and epsilon'/epsilon, and the electric dipole moment of the neutron. We fi nd the model to be tightly constrained by these parameters with several fin e-tuning conditions on the phases in the right-handed mixing matrix. There is also a necessarily non-zero value of the W-L-W-R mixing parameter, zeta( g). CP asymmetry phases in neutral B decays are discussed.
