Abstract

We study the effect of scalar leptoquarks on some rare decays of B_s mesons involving the quark level transition b\ensuremath→s l⁺l^\ensuremath-. In particular we consider the decays B_s\ensuremath→\ensuremathμ⁺\ensuremathμ^\ensuremath-, B_d⁰\ensuremath→X_s\ensuremathμ⁺\ensuremathμ^\ensuremath- and B_s\ensuremath→\ensuremathφ \ensuremathμ⁺\ensuremathμ^\ensuremath-. The leptoquark parameter space is constrained using the recently measured branching ratio of the B_s\ensuremath→\ensuremathμ⁺\ensuremathμ^\ensuremath- process at LHCb and CMS experiments. Using such parameters we obtain the branching ratio, forward-backward asymmetry and the CP asymmetry parameters in the angular distribution of B_s\ensuremath→\ensuremathφ \ensuremathμ⁺\ensuremathμ^\ensuremath- process.
