Measurements of ψ(2S) and X(3872) → J/ψ π+π- production in pp collisions at √s = 8 TeV with the ATLAS detector
Differential cross sections are presented for the prompt and non-prompt production of the hidden-charm states X(3872) and ψ(2S), in the decay mode J/ψπ+π −, measured using 11.4 fb−1 of pp collisions at √ s = 8 TeV by the ATLAS detector at the LHC. The ratio of cross sections X(3872)/ψ(2S) is also gi...
