We explore the possibility of simultaneous explanation of RK(*) and RD(*) measurements in a model dependent approach. We reanalysed the four new physics models: Standard model like vector boson (VB), SU(2)L-singlet vector leptoquark (U1), SU(2)L-triplet scalar leptoquark (S3) and SU(2)L triplet vector leptoquark (U3) models. The new physics couplings are assumed only to the third generation in the weak basis. We found that vector boson model is not consistent with the present data as the branching ratio of B(τ → 3μ) evades the upper bound on the best fit point. The three leptoquark models cannot simultaneously accomodate the RK (*) and RD(*) measurements. © Springer Nature Switzerland AG 2019.
