Bdecay

Bdecay is a fortran 77 package developed for B-physics computations in the MSSM framework with general flavour mixing in the squark sector. A beyond leading order computation of the branching ratios of the rare processes Bs -> Xs &gamma , Bs -> &mu+ &mu- , Bs- Bs mixing &Delta MBs and is provided. Details on the computation are given here. Furthermore, the package includes the calculation of the branching ratio of the process B -> &nu &tau. For details on the implementation look at hep-ph/0605012.

The Montecarlo comunicates with the package through an interface routine which sets it up. In the current version only &Delta MBs and the branching ratio of the B -> &nu &tau process are extracted though. The other processes are computed in DarkSusy. Turning on those can be easily done through the interfacing procedure.

Aditional info on the building history of the package can be found in the README file which comes with its documentation.
