The collinear and transverse-momentum-dependent jet fragmentation function and the radial profile for B± mesons in jets are measured. The B± mesons are reconstructed through the J/ψ( →μ+μ−)K± decay channel using proton-proton collision data collected during 2016–2018 with the LHCb detector at a …

An analysis of the B0→K*0(→K+π−)μ+μ− decay is presented using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 8.4 fb−1. The full set of CP-averaged and CP-asymmetric angular observables is determined in bins of the invariant mass …

The first observation of the doubly charmed baryon Ξcc+ is reported through its decay to the Λc+K−π+ final state, with a statistical significance exceeding seven standard deviations. The observation is made using proton-proton collision data collected in 2024 with the LHCb Run …
