$X(3872)\rightarrow{}J/\psi\pi^{+}\pi^{-}$ invariant mass distribution
This performance plots show the results for the observation of the $X(3872)\rightarrow{}J/\psi\pi^{+}\pi^{-}$ produced in pp collisions at $\sqrt{s}=7~\mathrm{TeV}$ using $40~\mathrm{pb}^{-1}$ data collected at the CMS detector, with the $\psi(2S)$ peak in the same channel as a reference. $J/\psi$...
