A Two Higgs Bi-doublet Left-Right Model With Spontaneous CP Violation
arXiv:0711.3891 · doi:10.1142/S0217751X0804202X
Abstract
We discuss a left-right symmetric model with two Higgs bi-doublet and spontaneous P and CP violation. The flavor changing neutral currents is suppressed by assuming approximate global U(1) family symmetry. We calculate the constraints from neural K meson mass difference Δm_K and demonstrate that a right-handed gauge boson W_2 contribution in box-diagrams with mass around 600 GeV is allowed due to a negative interference with a light charged Higgs boson around 150 \sim 300 GeV. The W_2 contribution to ε_K is suppressed from appropriate choice of additional CP phases appearing in the right-handed Cabbibo-Kobayashi-Maskawa(CKM) matrix. The model is found fully consistent with B^0 mass difference and the mixing-induced CP asymmetry measurements.
