    The B → K ∗ μμ decay exhibits deviations with respect to Standard Model expectations and the measurement of the ratio R K hints at a violation of lepton-flavour universality in B → K ℓℓ transitions. Both effects can be understood in model-independent fits as a short-dis...

    International audience; The determination of the fundamental parameters of the Standard Model (and its extensions) is often limited by the presence of statistical and theoretical uncertainties. We present several models for the latter uncertainties (random, nuisance, ex...

    The extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix from flavour observables can be affected by physics beyond the Standard Model (SM). We provide a general roadmap to take this into account, which we apply to the case of the Standard Model Effective Field Theo...

    We show that the decay rates of the Higgs boson to a pseudoscalar quarkonium and a pair of leptons, $h\to P\ell^+\ell^-$ ($P\in\{\eta_c,\eta_b\}$), can be substantially enhanced in a scenario with two Higgs doublets with a softly broken $\mathbb{Z}_2$ symmetry (2HDM) wh...

    In these mini-proceedings we review the results of the workshop `Impact of $B\to\mu^+\mu^-$ on New Physics Searches' that took place at the Paul Scherrer Institute (PSI) on the 18th-19th December 2017.

    The deviations with respect to the Standard Model that are currently observed in $b \to s \ell\ell$ transitions, or $B$ anomalies, can be interpreted in terms of different New Physics (NP) scenarios within a model-independent effective approach. We identify a set of int...

    In the absence of direct evidence for New Physics at present LHC energies, the focus is set on the anomalies and discrepancies recently observed in rare $b \to s\ell\ell$ transitions which can be interpreted as indirect hints. Global fits have shown that an economical N...
