Study of the Rare Decays(forumla presented)

Abstract

We study rare leptonic decays of vector B mesons in the scalar leptoquark and family non-universal odels. We constrain these new couplings by using the measured branching fractions of rocesses and the existing ixing data. We estimate the branching fractions of n both the models, which are found to be reasonably enhanced from their corresponding standard model values and within the reach of Run 2–3 of LHC.
