Search for the rare decay of charmed baryon Lambda+c into the p mu+ mu- final state

Observation of muonic Dalitz decays of chib mesons and precise spectroscopy of hidden-beauty states

The decays of the χb1(1P), χb2(1P), χb1(2P) and χb2(2P) mesons into the Υ(1S)μ+μ− final state are observed with a high significance using proton-proton collision data collected with the LHCb detector and corresponding to an integrated luminosity of 9 fb−1. The newly observed decays together with the Υ(2S) → Υ(1S)π+π− and Υ(3S) → Υ(2S)π+π− decay modes are used for precision measurements of the mass and mass splittings for the hidden-beauty states.

Study of charmonium production via the decay to pp¯ at √s=13TeV

Charmonium production cross-section in proton–proton collisions is measured at the centre-of-mass energy s=13TeV using decays to pp¯ final state. The study is performed using a data sample corresponding to an integrated luminosity of 2.2fb-1 collected in 2018 with the LHCb detector. The production cross-section of the ηc meson is measured in a rapidity range of 2.0<4.0 and in a transverse momentum range of 5.0<20.0GeV/c, which is extended compared with previous LHCb analyses. The differ...

Comprehensive analysis of local and nonlocal amplitudes in the B0→ K*0μ+μ− decay

A comprehensive study of the local and nonlocal amplitudes contributing to the decay B0 → K*0(→ K+π−)μ+μ− is performed by analysing the phase-space distribution of the decay products. The analysis is based on pp collision data corresponding to an integrated luminosity of 8.4 fb−1 collected by the LHCb experiment. This measurement employs for the first time a model of both one-particle and two-particle nonlocal amplitudes, and utilises the complete dimuon mass spectrum without any veto regions...

Study of the rare decay J/ψ → μ+μ−μ+μ−

The rare electromagnetic J/ψ → μ+μ−μ+μ− decay is observed with a significance greatly exceeding the discovery threshold, using proton-proton collision data collected by the LHCb experiment during 2016–2018 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb−1. The rate of this decay is measured relative to that of the J/ψ → μ+μ− mode. Using the QED model for the four-muon decay in the efficiency estimation, its branching fraction is determined to be (Form...
