Measurement of the X(3872) production cross section via decays to $J/\psi \pi^{+}\pi^{-}$
The production of the X(3872) is studied in $pp$ collisions at $\sqrt{s} = 7$ TeV with the CMS detector at LHC, using decays to $J/\psi\pi^{+}\pi^{-}$ where the $J/\psi$ decays to two muons. The cross-section ratio with respect to the $\psi(2S)$ and the fraction of X(3872) coming from B-hadron decay...
