Abstract

Motivated by the recent measurements of the B_s - over(B, ̄)_s mass difference from the DØ and CDF Collaborations, we probe new physics effects in the B_q - over(B, ̄)_q mixing within the context of the supersymmetric grand unified model (SUSY GUT). We find that new physics effects in B_{s (d)} - over(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.
