Long distance contribution to $B^{-}\to K^{-}{K}^{-}{\pi }^{+}$, - a searching ground mode for new physics

Abstract

The decay $B^{-}\to K^{-}{K}^{-}{\pi }^{+}$ has been sugested as a test for minimal supersymmetric standard model and for supersymmetric models with R-parity violating couplings, in view of its extreme smallnesss in the standard model. We calculate two long distance contributions to this decay, that associated with $DD$ and $D\pi$ intermediate states and that induced by virtual $D$, $\pi$ mesons. The branching ratio due to these contributions is $6\times 10^{-12}$, which is somewhat smaller than the standard model short distance result, leaving this decay free for the search of new physics.
