A bstract Rare b hadron decays are considered excellent probes of new semileptonic four-
fermion interactions of microscopic origin. However, the same interactions also correct the …

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 …

In light of the very recent updates on the R_K RK and R_ K^* RK∗ measurements from the
LHCb and Belle collaborations, we systematically explore here imprints of New Physics in b …

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 …

We revisit the possibilities of accommodating the experimental indications of the lepton
flavor universality violation in b-hadron decays in the minimal scenarios in which the …

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 …

Lepton number as a fourth color is an intriguing theoretical idea which is combined with a
possible left-right symmetry within the famous Pati-Salam (PS) model. In the conventional …

We discuss the status of b→ s ℓ+ ℓ-decays in the post-RK (*) era. The recent LHCb update of
RK and RK* measurements, which are now compatible with the Standard Model, constrain …

A bstract The three-site Pati-Salam gauge model provides a consistent description for the
hints of lepton-flavor non-universality observed in B decays, connecting the present pattern …

Abstract wilson is a Python library for matching and running Wilson coefficients of higher-
dimensional operators beyond the Standard Model. Provided with the numerical values of …
