英文摘要:
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 Delta m(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 similar to 300 GeV. The W-2 contribution to epsilon(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.
