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

Charged lepton flavour-violating transitions would be a clear signal of new physics beyond
the Standard Model. Their search has been carried out in a variety of channels, the most …

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 standard model of particle physics currently provides our best description of
fundamental particles and their interactions. The theory predicts that the different charged …

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 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 …

The first simultaneous test of muon-electron universality using B+→ K+ ℓ+ ℓ-and B 0→ K* 0
ℓ+ ℓ-decays is performed, in two ranges of the dilepton invariant-mass squared, q 2. The …

The ratio of the B s 0 and B 0 fragmentation fractions, fs/fd, in proton-proton collisions at the
LHC, is obtained as a function of B-meson transverse momentum and collision center-of …
