A COMPARATIVE STUDY ON B →K*ℓ+ ℓ- AND 
DECAYS IN THE SUPERSYMMETRIC MODELS
Abstract
In this paper, we compare the branching ratio and rate difference of electron channel to muon channel of 
and B →K*ℓ+ℓ- decays, where 
is the p-wave scalar meson, in the supersymmetric models. MSSM with R parity is considered since considerable deviation from the standard model predictions can be obtained in B→Xs ℓ-ℓ+. Taking CQ1 and CQ2 about one which is consistent with the B→K*μ+μ- rate at low dileptonic invariant mass region (1 ≤ q2 ≤ 6 GeV2). It is found that, firstly, the 
decay is measurable at LHC, secondly, in comparison with B →K*ℓ+ ℓ- decay a greater deviation in the 
decay can be seen. Measurement of these observables for the semileptonic rare 
, in particular, at low q2 region can give valuable information about the nature of interactions within Standard Model or beyond.
