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 …

A bstract Three searches are presented for signatures of physics beyond the standard model
(SM) in ττ final states in proton-proton collisions at the LHC, using a data sample collected …

A bstract We consider the constraints from Supernova 1987A on particles with small
couplings to the Standard Model. We discuss a model with a fermion coupled to a dark …

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 …

We review the current status and implications of the anomalies (ie deviations from the
Standard Model predictions) in semi-leptonic B meson decays, both in the charged and in …

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 …

The ratio of branching fractions R (D*-)≡ B (B 0→ D*-τ+ ν τ)/B (B 0→ D*-μ+ ν μ) is measured
using a data sample of proton-proton collisions collected with the LHCb detector at center-of …
