ΔS = 2 Decays of B- Meson

The ΔS = 2 transitions of the B mesons in the Standard Model are very rare.We investigate the three - body B- → K - K -π+ and two - body B - → K *- K*0, B - → K - K 0, B - → K *- K 0, B - → K - K*0 decays in the Standard Model and in the Minimal Supersymmetric Model with and without R parity conservation. All five modes are found to have branching ratios of the order of 10-13- 10-11 in the Standard Model, while the expected branching ratio in the different extensions vary between 10-9 - 10-6, for a reasonable set of assumed parameters.
