Abstract
We re-consider recent measures of RK and RK⁎, now compatible with the Standard Model expectations, as well as the results for the process BR(Bs→μ+μ−) alongside earlier determinations of RD(⁎) and BR(Bc→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.
