Solving the SUSY CP problem with flavor breaking F-terms
Abstract
Supersymmetric flavor models for the radiative generation of fermion masses offer an alternative way to solve the SUSY CP problem. We assume that the supersymmetric theory is flavor and CP-conserving. CP violating phases are associated to the vacuum expectation values of flavor violating susy-breaking fields. As a consequence, phases appear at tree level only in the soft supersymmetry breaking matrices. Using a U(2) flavor model as an example we show that it is possible to generate radiatively the first and second generation of quark masses and mixings as well as the CKM CP phase. The supersymmetric contributions to EDMs are automatically zero since all the relevant parameters in the lagrangian are flavor conserving and as a consequence real. The size of the flavor and CP mixing in the susy breaking sector is mostly determined by the fermion mass ratios and CKM elements. We calculate the contributions to epsilon, epsilon' and to the CP asymmetries in several B decays and study their respective constraints on the squark spectra.Keywords
