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 …

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 …

An angular analysis of the B 0→ K* 0 (→ K+ π-) μ+ μ-decay is presented using a dataset
corresponding to an integrated luminosity of 4.7 fb-1 of pp collision data collected with the …

We present an angular analysis of the B+→ K*+(→ KS 0 π+) μ+ μ-decay using 9 fb-1 of pp
collision data collected with the LHCb experiment. For the first time, the full set of CP …

An angular analysis of the B0→ K* 0 (→ K+ π−) μ+ μ− decay is presented using a dataset
corresponding to an integrated luminosity of 4.7 fb− 1 of pp collision data collected with the …

The LHCb Upgrade II will fully exploit the flavour-physics opportunities of the HL-LHC, and
study additional physics topics that take advantage of the forward acceptance of the LHCb …

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 …

Following the updated measurement of the lepton flavour universality (LFU) ratio R_K RK in
B → K ℓ ℓ B→ K ℓ ℓ decays by LHCb, as well as a number of further measurements, eg R …
