Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Recent measurements of b-hadron decays show a pattern of consistent tensions with the
respective Standard Model (SM) predictions. These tensions appear both in the sector of …

This paper reports world averages of measurements of b-hadron, c-hadron, and τ-lepton
properties obtained by the Heavy Flavor Averaging Group using results available before …

The anomalies in rare B decays endure. We present results of an updated global analysis
that takes into account the latest experimental input–in particular the recent results on\(R_K\) …

The LHCb Collaboration has recently released a new study of B+→ K+ ℓ+ ℓ-and B→ K* 0 ℓ+
ℓ-(ℓ= e, μ) decays, testing lepton universality with unprecedented accuracy using the whole …

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 …

Branching fraction and effective lifetime measurements of the rare decay B s 0→ μ+ μ-and
searches for the decays B 0→ μ+ μ-and B s 0→ μ+ μ-γ are reported using proton-proton …

An improved measurement of the decay B s 0→ μ+ μ-and searches for the decays B 0→ μ+
μ-and B s 0→ μ+ μ-γ are performed at the LHCb experiment using data collected in proton …

Motivated by renewed evidence for new physics in b→ s ℓ ℓ transitions in the form of LHCb's
new measurements of theoretically clean lepton-universality ratios and the purely leptonic B …

Recently the LHCb collaboration has confirmed the evidence for lepton flavour
nonuniversality at the 3.1σ level via an updated measurement of R K. In this work we …
