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 …

This paper presents a study of the charmless three-body decays B(s)0 → KS0h+h′− (where h(′) = π, K), using a sample of pp collision data collected by the LHCb experiment during Runs 1 and 2 of the LHC, corresponding to an integrated …

A flavor-tagged time-dependent analysis of B0→KS0μ+μ− decays is performed across the full dimuon mass range excluding the J/ψ and ψ(2S) resonance regions. The analysis uses proton-proton collision data collected by the LHCb experiment in 2011–2018 at center-of-mass energies of 7, 8, and …

Charged-hadron distributions in heavy-flavor jets are measured in proton-proton collisions at a center-of-mass energy of s=13$$ \sqrt{s}=13 $$ TeV collected by the LHCb experiment. Distributions of the longitudinal momentum fraction, transverse momentum, and radial profile of charged hadrons are measured separately in …

A sample of pp collision data, corresponding to an integrated luminosity of 5.4 fb−1 and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of the lifetime of the Ξb0 baryon to that of the Λb0 …

The Λb0 → Λc+Ds−K+K− decay is observed for the first time using the data sample from proton-proton collisions recorded at a center-of-mass energy of 13 TeV with the LHCb detector, corresponding to an integrated luminosity of 6 fb−1. The ratio of branching …

An angular analysis of B0 → K∗0e+e− decays is presented using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb−1. The analysis is performed in the …

This paper presents the first measurement of ψ(2S) and χc1(3872) meson production within fully reconstructed jets. Each quarkonium state (tag) is reconstructed via its decay to the J/ψ(→μ+μ−)π+π− final state in the forward region using proton-proton collision data collected by the LHCb …

We report a dedicated study of the newly discovered extended UHE γ-ray source 1LHAASO J0056+6346u. Analyzing 979 d of LHAASO-WCDA data and 1389 d of LHAASO-KM2A data, we observed a significant excess of γ-ray events with both WCDA and KM2A. Assuming a …

An amplitude analysis of the Ds1(2460)+→Ds+π+π- transition is performed simultaneously in B0→D-Ds+π+π-, B+→D0Ds+π+π-, and B0→D*-Ds+π+π- decays. The study is based on a data sample of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of s=7,8, and 13 TeV, corresponding to …
