A CP violating mixing matrix compatible with neutral flavour conservation and spontaneous CP violation
Description
A specific ansatz for the Yukawa couplings of a four-generation SU(2)L x U(I) model with two Higgs doublets is discussed which leads to neutral flavour conservation, spontaneous CP violation and to a genuinely complex mixing matrix. W exchange conserves CP in the limit mt' = mt only. The decay rate for t → b is reduced by a factor two compared to the Standard Model with three generations. The phenomenological implications for K0-K-bar0 and B0-B-bar0 are investigated. (Author)
