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 …

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” …

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 …

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 …

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\(R_K\) …

Tests of lepton universality in B 0→ KS 0 ℓ+ ℓ-and B+→ K*+ ℓ+ ℓ-decays where ℓ is either an
electron or a muon are presented. The differential branching fractions of B 0→ KS 0 e+ e …

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 …

In response to the 2013 Update of the European Strategy for Particle Physics, the Future
Circular Collider (FCC) study was launched, as an international collaboration hosted by …

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 …
