Abstract

We re-consider recent measures of R_K and R_K^*, now compatible with the Standard Model expectations, as well as the results for the process BR(B_s → μ⁺ μ^-) alongside earlier determinations of R_D^(∗) and BR(B_c → τν). We provide analytic constraints on the associated Wilson coefficients in both the b → s and the b → c sectors. These allow us to estimate the scale of potential New Physics for generic extensions of the Standard Model. We then use the results to constrain the leptoquark landscape.
