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.
