Abstract

Motivated by the recent measurements of the Bs-Bs mass difference from the D0 and CDF collaborations, we probe new physics effects in the Bq-Bq mixing within the context of the supersymmetric grand unified model (SUSY GUT). We find that new physics effects in Bs(d)-Bs(d) mixing lead to the correlated information in the branching fractions of the lepton flavor violating decays, which may serve as a test of the SUSY GUT. We also discuss the implication of such new physics effects on the quark-lepton complementarity in the neutrino mixings.
