Abstract
Motivated by the recent measurements of the Bs−B¯s mass difference from the DØ and CDF Collaborations, we probe new physics effects in the Bq−B¯q mixing within the context of the supersymmetric grand unified model (SUSY GUT). We find that new physics effects in Bs(d)−B¯s(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.
