Abstract: We study the rare semileptonic decays of B mesons induced by as well as transitions in the scalar leptoquark (LQ) model, where the LQs have the representation (3, 2, 7/6) and (3, 2, 1/6) under the standard model gauge group. The LQ parameter space is constrained using the most recent experimental results on and processes. Considering only the baryon number conserving LQ interactions, we estimate the branching ratios for the exclusive and inclusive decay processes by using the constraint parameters. We also obtain the low recoil (large lepton invariant mass, i.e., ) predictions for the angular distribution of process and several other observables including the flat term and lepton flavour non-universality factor in this model.
