In this paper, we compare the branching ratio and rate difference of electron channel to muon channel of [Formula: see text] and B →K*ℓ + ℓ - decays, where [Formula: see text] 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→X s ℓ - ℓ + . Taking C Q1 and C Q2 about one which is consistent with the B→K*μ + μ - rate at low dileptonic invariant mass region (1 ≤ q 2 ≤ 6 GeV 2 ). It is found that, firstly, the [Formula: see text] decay is measurable at LHC, secondly, in comparison with B →K*ℓ + ℓ - decay a greater deviation in the [Formula: see text] decay can be seen. Measurement of these observables for the semileptonic rare [Formula: see text], in particular, at low q 2 region can give valuable information about the nature of interactions within Standard Model or beyond.
