28 Jun 2002 | | Journal: | Eur.Phys.J. C25 (2002) 615-622 | | Subject: | hep-ph | | Affiliation: | Korea Inst. Sci., Daejeon), G. Kramer (Hamburg U. | | Abstract: | We consider the gluino-mediated SUSY contributions to B0 - B0 bar mixing, B -> J/psi K_S and B -> X_d gamma in the mass insertion approximation. We find the LL mixing parameter can be as large as |delta_{13}^d_{LL}| < 2*10^-1, but the LR mixing is strongly constrained by the B -> X_d gamma branching ratio and we find |delta_{13}^d_{LR}| < 10^-2. The implications for the direct CP asymmetry in B -> X_d gamma and the dilepton charge asymmetry (A_{ll}) are also discussed, where substantial deviations from the standard model predictions are possible. | | Source: | arXiv, hep-ph/0206297 | | Other source: | [GID 801374] hep-ph/0211182 | | Services: | Forum | Review | PDF | Favorites | |
