A bstract We provide improved Standard Model theory predictions for the exclusive rare
semimuonic processes B→ K (*) μ+ μ− and B s→ ϕμ+ μ−. Our results are based on a novel …

We discuss the impact of the recent LHCb update on the two lepton-flavour universality
ratios RK and RK∗, and the CMS update of B (B s→ μ+ μ-) regarding the possibility of New …

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 …

A bstract Motivated by the recent LHCb announcement of a 3. 1σ violation of lepton-flavor
universality in the ratio RK= Γ (B→ Kμ+ μ−)/Γ (B→ Ke+ e−), we present an updated …

Measurements are presented of the B $^ 0_\mathrm {S} $$\to $$\mu^+\mu^-$ branching
fraction and effective lifetime, as well as results of a search for the B $^ 0$$\to $$\mu^+\mu …

A bstract An angular analysis and a measurement of the differential branching fraction of the
decay B 0 s→ ϕμ+ μ− are presented, using data corresponding to an integrated luminosity …

A bstract Anomalies in semileptonic B-meson decays present interesting patterns that might
be revealing the shape of the new physics to come. Under the assumption that neutrino and …

A bstract An angular analysis of the rare decay\({B} _s^ 0\)→ ϕμ+ μ− is presented, using
proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of …

A bstract We critically reassess the theoretical uncertainties in the Standard Model
calculation of the B→ K∗ ℓ+ ℓ− observables, focusing on the low q 2 region. We point out …

A bstract We develop an economical theoretical framework for combined explanations of the
flavor physics anomalies involving muons:(g− 2) μ,\({R} _ {K^{\left (\ast\right)}}\), and b→ sμ+ …
