Abstract

New results in processes with an underlying quark transition bs+b\to s \ell^+\ell^- have been recently reported by the LHCb and Belle II collaborations. In this note we show how the main implications of a handful of new measurements can be understood with the tools introduced in our recent paper, arXiv:1811.10793, without the need to redo the global fits. We find that the main impact of the new results, due to RK[1.1,6]R_K^{[1.1,6]} from LHCb, is a decrease in C10μNPC_{10\mu}^{NP} with a reduced uncertainty. We validate this conclusion by presenting the result of a new global fit.
