b{yields}s{nu}{nu} decay in the MSSM: Implication of b{yields}s{gamma} at large tan{beta}
- Department of Physics, Tohoku University, Sendai 980-8578 (Japan)
The decay b{yields}s{nu}{nu} is discussed in the minimal supersymmetric standard model with general flavor mixing for squarks, at large tan{beta}. In this case, in addition to the chargino loop contributions which were analyzed in previous studies, tan{beta}-enhanced contributions from the gluino and charged Higgs boson loops might become sizable compared with the standard model contribution, at least in principle. However, it is demonstrated that the experimental bounds on the new physics contributions to the radiative decay b{yields}s{gamma} should strongly constrain these contributions to b{yields}s{nu}{nu}, especially on the gluino contribution. We also briefly comment on a possible constraint from the B{sub s}{yields}{mu}{sup +}{mu}{sup -} decay.
