CP Violation in B_s Mixing in the SUSY SU(5) GUT with Right-handed Neutrinos

It is recently announced by the {\bf Ut}{\it fit} collaboration that the CP phase of the $B_s$ mixing amplitude, $\phi_{B_s}$, deviates more than $3 \sigma$ from the standard-model prediction. In this paper we discuss how large correction to $\phi_{B_s}$ is possible in the supersymmetric SU(5) ground unified model (SUSY SU(5) GUT) with right-handed neutrinos. Here, we assume the supergravity-like boundary condition for the SUSY-breaking terms. We found that the 95% probability region derived by the {\bf Ut}{\it fit} collaboration is marginal in this model.Comment: 13 pages, 13 figures, version to appear in PL

Flavor and CP Violation Induced by Atmospheric Neutrino Mixing

Neutrino oscillation experiments suggest existence of new flavor-violating interactions in high energy scale. It may be possible to probe them by the flavor- and CP-violating processes in leptons and hadrons in the supersymmetric (SUSY) models. In this article the third-generation flavor violation is reviewed in the SUSY seesaw model and SUSY SU(5) GUT with the right-handed neutrinos.Comment: 12 pages.
