Antihelium production in ¯Λ0b decays
/LHCb Collaboration
Decays of ¯Λ0b baryons produced in dark matter annihilating into b¯b pairs could enhance the abundance of antihelium in cosmic rays. The LHCb collaboration provides in this paper the first experimental limits on related branching fractions: B(¯Λ0b→3¯Hepp)<1.9×10−9 at 90% CL,B(¯Λ0b→3¯HeppX)<1.6×10−8 at 90% CL,B(¯Λ0b→3¯HepX)<3.6×10−8 at 90% CL, where X denotes one or several particles.

Search for B∗0(s)→μ+μ− in B+c→π+μ+μ− decays
/LHCb Collaboration
A search for the very rare B∗0→μ+μ− and B∗0s→μ+μ− decays is conducted by analysing the B+c→π+μ+μ− process. The analysis uses proton-proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9\,fb−1. [...]

Observation of the rare decay J/ψ→μ+μ−μ+μ−
/LHCb Collaboration
The rare electromagnetic decay J/ψ→μ+μ−μ+μ− is observed with significance greatly exceeding the discovery threshold, using the proton-proton collision data collected by the LHCb experiment in 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 J/ψ→μ+μ− mode. [...]

Measurement of CP asymmetry in B0s→D∓sK± decays
/LHCb Collaboration
A measurement of the CP-violating parameters in B0s→>D∓sK± decays obtained from pp collisions is reported, using a data set corresponding to an integrated luminosity of 6fb−1 at a centre-of-mass energy of √s=13TeV recorded with the LHCb detector between 2015 and 2018. The measured values are: > Cf=+0.791±0.061±0.022,AΔΓf=−0.051±0.134±0.037,AΔΓˉf=−0.303±0.125±0.036,Sf=−0.571±0.084±0.023,Sˉf=−0.503±0.084±0.025, where the uncertainties are statistical and systematic, respectively.
