We study the decay rate of the process B→Kl + l − (l=e,μ) and some of its other related observables, like the forward–backward asymmetry (A FB), polarization asymmetry (PA), double branching ratio and CP asymmetry (A CP) in the R-parity violating Minimal Supersymmetric Standard Model ( MSSM). We have performed an error analysis of the differential branching fraction, A FB and CP asymmetry. The analysis shows that theoretical results based on MSSM as an additional effect are compatible with the standard model. A FB is found to be zero, in agreement with SM. The average A CP is not only found to be significant in comparison with SM, but it is also compatible with the measured value within errors.
