Abstract
It is recently announced by the UTfit Collaboration that the CP phase of the Bs mixing amplitude, ÏBs, deviates more than 3Ï from the Standard Model prediction. In this Letter we discuss how large correction to ÏBs 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 UTfit Collaboration is marginal in this model.
