Description

A measurement of the ratio of $X(3872)$ and $\psi(2S)$ signal yields in $pp$ collisions at 7 TeV is presented, using data recorded at the CMS experiment in 2010 corresponding to an integrated luminosity of 36pb-1. The events are reconstructed decays into $J/\psi \pi^+ \pi^-$ and subsequent decay of the $J/\psi$ candidates into two muons. The measured ratio is compared to theoretical expectations.
