Observation of the B s 0 → X ( 3872 ) ϕ Decay
© 2020 CERN. Using a data sample of proton-proton collisions at s=13 TeV, corresponding to an integrated luminosity of 140 fb-1 collected by the CMS experiment in 2016-2018, the Bs0→X(3872)φ decay is observed. Decays into J/ψ+π- and K+K- are used to reconstruct, respectively, the X(3872) and φ. The...
