Today, at the Rencontres de Moriond QCD and High Energy Interactions, the LHCb collaboration reported the observation of the rare elecromagnetic decay J/ψ→μ+μ–μ+μ–. The simultaneous discovery of the J/ψ meson…
The LHCb collaboration submitted its 700th publication! The paper reports the integrated and differential cross-section measurements of associated J/ψ and ψ(2S) production in proton-proton collisions at 13TeV, the measurement is…
