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 …

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 Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-
energy extensions of the Standard Model (SM). We investigate the phenomenology of an …

A bstract We present a considerably improved analysis of model-independent bounds on
new physics effects in non-leptonic tree-level decays of B-mesons. Our main finding is that …

The LHCb measurements of the μ/e ratio in B→ K ℓ ℓ decays (RK) indicate a deficit with
respect to the Standard Model prediction, supporting earlier hints of lepton universality …

Belle II has reported the first evidence for B+→ K+ ν ν¯ with a branching ratio 2.7 σ higher
than the standard model expectation. We explain this and the MiniBooNE and muon …

Mesons comprising a beauty quark and strange quark can oscillate between particle (B s 0)
and antiparticle (B¯ s 0) flavour eigenstates, with a frequency given by the mass difference …

We analyze the recent hints of lepton flavor universality violation in both charged-current
and neutral-current rare decays of B mesons in an R-parity-violating supersymmetric …

In this article, we review the current status of B-mixing and b-hadron lifetimes both from
experimental and theoretical points of view. Furthermore, we discuss the phenomenological …

We reemphasize the strong dependence of the branching ratios $ B (K^+\to\pi^+\nu\bar\nu)
$ and $ B (K_L\to\pi^ 0\nu\bar\nu) $ on $| V_ {cb}| $ that is stronger than in rare $ B …
