Global flavour fits to rare B decay observables

Type: conference-paper
Abstract: We explore the current status of decays involving $b \to s \ell^+\ell^-$ transitions. The recent LHCb update on measurements of $R_K$ and $R_{K^*}$ indicates compatibility with the Standard Model, restricting potential contributions from new physics to adhere to lepton flavour universality. In addition to the latest LHCb measurements of $R_K$ and $R_{K^*}$, we incorporate recent CMS measurements of both $R_K$ and the branching ratio of $B^+ \to K^+ \mu^+\mu^-$. Our analysis adopts a model-independent approach to scrutinise the $b\to s \ell^+ \ell^-$ data, examining the implications of various sets of observables. Furthermore, we explore multi-dimensional fits, assessing the significance of more complex new physics scenarios in comparison to simpler one- and two-dimensional scenarios.
