Measurement of the branching fraction of B0J/ψπ0 decays / LHCb Collaboration
The ratio of branching fractions between B0J/ψπ0 and B+J/ψK+ decays is measured with proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb1. The measured value is BB0J/ψπ0BB+J/ψK+=(1.153±0.053±0.048)×102, where the first uncertainty is statistical and the second is systematic. [...]

Observation of muonic Dalitz decays of χb mesons and precise spectroscopy of hidden-beauty states / LHCb Collaboration
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 9fb1. 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 the rare decay J/ψμ+μμ+μ / LHCb Collaboration
The rare electromagnetic J/ψμ+μμ+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 5.4fb1. The rate of this decay is measured relative to that of the J/ψμ+μ mode. [...]

Search for CP violation in the phase space of D0K0SK±π decays with the energy test / LHCb Collaboration
A search for CP violation in D0K0SK+π and D0K0SKπ+ decays is reported. The search is performed using an unbinned model-independent method known as the energy test that probes local CP violation in the phase space of the decays. [...]

Amplitude analysis of the Λ0bpKγ decay / LHCb Collaboration
The resonant structure of the radiative decay Λ0bpKγ in the region of proton-kaon invariant-mass up to 2.5 GeV/c2 is studied using proton-proton collision data recorded at centre-of-mass energies of 7, 8, and 13 TeV collected with the LHCb detector, corresponding to a total integrated luminosity of 9 fb1. Results are given in terms of fit and interference fractions between the different components contributing to this final state. [...]
