K0-(K)BAR0 IN THE SU(2)LXSU(2)RXU(1) MODEL OF CP VIOLATION

We reexamine the K0-K0BAR system in the SU(2)L X SU(2)R X U(1) model of CP violation with three generations with special emphasis on the minimal model of spontaneous CP violation. We give a new estimation of the hadronic matrix elements entering in epsilon'/epsilon, taking into account constraints from current algebra, final-state interactions, and short-distance QCD corrections. We compute, for an arbitrary number of generations, the phenomenological CP phases in terms of the quark masses, the parameter r (ratio of Higgs vacuum expectation values), and the single CP phase alpha of the model. We make a three-generation phenomenological analysis taking into account the high multiplicity of the sheets for the CP phases and the uncertainties in the Kobayashi-Maskawa matrix elements and m(t). For low M(WR) the two-generation LR part dominates for most of the solutions, but the pure L three-generation contribution can be dominant in some cases.
