At the present time (2022), there are discrepancies with the predictions of the Standard
Model in several observables involving b→ s ℓ+ ℓ− and decays. These are the B flavor …

Following the updated measurement of the lepton flavour universality (LFU) ratio R_K RK in
B → K ℓ ℓ B→ K ℓ ℓ decays by LHCb, as well as a number of further measurements, eg R …

flavio is an open source tool for phenomenological analyses in flavour physics and other
precision observables in the Standard Model and beyond. It consists of a library to compute …

There are four models of tree-level new physics (NP) that can potentially simultaneously
explain the b→ s μ+ μ-and b→ c τ-ν¯ anomalies. They are the S 3, U 3 and U 1 leptoquarks …

The anomalies in the measurements of observables involving b→ sμμ decays, namely RK,
RK*, P 5′, and B s ϕ, may be addressed by adding lepton-universality-violating new …

A bstract Based on recent HQET sum rule and lattice calculations we present updated
Standard Model predictions for the mass differences of neutral B mesons:\(\varDelta {M} …

A bstract We present a considerably improved analysis of model-independent bounds on
new physics effects in non-leptonic tree-level decays of B-mesons. Our main finding is that …

The recent measurement of RK* is yet another hint of new physics (NP) and supports the
idea that it is present in b→ s μ+ μ-decays. We perform a combined model-independent and …

We investigate the implications of the latest LHCb measurement of RK for NP explanations
of the B anomalies. The previous data could be explained if the b→ s μ+ μ− NP is in (I) C 9 …

Many new physics models that explain the intriguing anomalies in the b-quark flavor sector
are severely constrained by B s mixing, for which the Standard Model prediction and …
