We evaluate two-body decay modes of charginos in the Minimal Supersymmetric Standard Model with complex parameters (cMSSM). Assuming heavy scalar quarks we take into account all decay channels involving charginos, neutralinos, (scalar) leptons, Higgs bosons and Standard Model gauge bosons. The...

We study the effect of Zâ€²-mediated flavor-changing neutral current on the B â†’ Ï€Ï€ decays. The branching ratios of these decays can be enhanced remarkably in the nonuniversal Zâ€² model. Our estimated branching ratios B( B â†’ Ï€ Ï€) are enhanced significantly...

We carried out a model independent search for an exotic three-body decay of orthopositronium o-Ps Î³ + X[sub 1] + X[sub 2] into a photon and two weak interacting particles X[sub 1] and X[sub 2] . The existence of this decay could explain the discrepancy between the measured and the...

We prove sharp pointwise t decay for scalar linear perturbations of a Schwarzschild black hole without symmetry assumptions on the data. We also consider electromagnetic and gravitational perturbations for which we obtain decay rates t, and t, respectively. We proceed by decomposition into...

The achievable precision of the cross section times branching ratio measurement from the event rates is estimated for the MSSM H/A decay in the associated production process gg at large tan in CMS. This work demonstrates that the above production and decay process exhibit a large sensitivity to...
