Enhancement of Br(B-d -> mu(+)mu(-))/Br(B-s -> mu(+)mu(-)) in supersymmetric unified models Academic Article uri icon


  • 2015 American Physical Society. We explain the 2.3 deviation in the recent measurements of the neutral B meson decays into muon pairs from the standard model prediction in the framework of supersymmetric grand unified models using antisymmetric coupling as a new source of flavor violation. We show a correlation between the Bd+- decay and the CP phase in the BdJ/K decay and that their deviations from the standard model predictions can be explained after satisfying constraints arising from various hadronic and leptonic rare decay processes, B-B, K-K oscillation data, and electric dipole moments of electron and neutron. The allowed parameter space is typically represented by pseudoscalar Higgs mass mA1 TeV and tanH(vu/vd)a 20 for squark and gluino masses around 2 TeV.
