Measurement of the production cross section ratio of X(3872) and psi(2S) in the decays to J/psi pi+ pi- in pp collisions at sqrt(s) = 7 TeV
A measurement of the ratio of the production cross sections for the $X(3872)$ and the $\psi(2S)$ resonances in $pp$ collisions at 7 TeV, using data recorded with the CMS experiment in 2010 corresponding to an integrated luminosity of 40 pb$^{-1}$, is presented. The resonances are reconstructed in th...
