The recently reported branching ratio (BR) for the 4+ state in 18Ne at Ex = 7.06 MeV strongly disagrees with the BR computed using the known properties of this state.

We calculate the inclusive charmless semileptonic decay width of the B meson using a QCD-based approach. This approach is able to account for both dynamic and kinematic effects of nonperturbative QCD. The charmless semileptonic decay width is found to be enhanced by long-distance strong interactions by +(7± 5)% with respect to the free quark decay width. Using the resulting theoretical value fo...

The branching ratios for the neutral and charged B decay channels to ηK and ηK are well above the Standard Model expectations. Moreover, the mixing-induced CP asymmetry in B → φKS is incompatible to that found in B → J/ψKS . We investigate whether a flavourspecific tree-level b → sss operator coming from R-parity violating supersymmetry can resolve both these discrepancies, without jeopardizing...

Results are given of a reanalysis of some data from a Bevatron experiment on the decay modes Kl i-++ +-? +-r 7r, rp v, 7~ e v, andp ~1.

We present the manual for the program BRIDGE: Branching Ratio Inquiry/Decay Generated Events. The program is designed to operate with arbitrary models defined within matrix element generators, so that one can simulate events with small finalstate multiplicities, decay them with BRIDGE, and then pass them to showering and hadronization programs. BRI can automatically calculate widths of two and ...

The b → s ll process is studied in the minimal supergravity model in detail. Taking account of the long distance contributions from the cc resonances, we calculate the branching ratio and the lepton forward-backward asymmetry in this model. We find that there is a strong correlation between the branching ratios of b → s γ and b → s ll processes and that the interference effect can change the b ...
