Measurements of $\psi$(2S) and $X$(3872)$\to\,J/\psi\,\pi^{+}\pi^{-}$ with the ATLAS detector
Differential cross sections are presented for the prompt and non-prompt production of the hidden-charm state X(3872) and of $\psi$(2S), in the decay mode J/$\psi \pi^+ \pi^-$, measured at $\sqrt{s}$ = 8 TeV by the ATLAS detector at LHC. In the non-prompt production, the data suggest the presence of...
