A Two Higgs Bi-doublet Left-Right Model With Spontaneous CP Violation

Understand

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 \sim 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.
