ΔS = 2 decays of B− meson in MSSM and two Higgs doublet model

Abstract In view of the extreme smallness of ΔS = 2 transitions of B meson in the Standard Model, we consider their occurence in several extensions of it. Thus, we analyze the three - body B− → K− K− π+ and two - body B− → K*− K*0, B− → K− K0, B− → K*− K0, B− → K− K*0 decay modes both in the Standard Model and in the Minimal Supersymmetric Model with and without R parity conservation and in two Higgs doublet models. All five modes are found to have a branching ratio of the order of 10−13 in the Standard Model, while the expected branching ratio in the different extensions vary between 10−9 - 10−6, for a given reasonable choice of parameters.
