Abstract

We study the impact of vector leptoquarks on the recent anomalies in semileptonic B meson decays such as R_K and R_D^(*) etc. We constrain the leptoquark couplings by using the existing data on the branching ratios of B_s → l⁺ l^- and B → X_s l⁺ l^- processes, where l=e,μ,τ. We estimate the branching ratios of B → D^(*) l ν_l processes using the constrained leptoquark parameter space. We also investigate the possibility of simultaneous explanation of R_D^(*), R_K anomalies in this model.
