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 …

An improved measurement of the decay B s 0→ μ+ μ-and searches for the decays B 0→ μ+
μ-and B s 0→ μ+ μ-γ are performed at the LHCb experiment using data collected in proton …

First evidence of a structure in the $ J/\psi\varLambda $ invariant mass distribution is
obtained from an amplitude analysis of $\varXi_b^-\to J/\psi\varLambda K^-$ decays. The …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …

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 …

The production fractions of B¯ s 0 and Λ b 0 hadrons, normalized to the sum of B-and B¯ 0
fractions, are measured in 13 TeV pp collisions using data collected by the LHCb …

The first observation of the decays B (s) 0→ J/ψ pp¯ is reported, using proton-proton
collision data corresponding to an integrated luminosity of 5.2 fb-1, collected with the LHCb …

A search for the rare decays B s 0→ μ+ μ-and B 0→ μ+ μ-is performed at the LHCb
experiment using data collected in pp collisions corresponding to a total integrated …
