Abstract
This article presents the cross-section ratio Ï(Ïc2)/Ï(Ïc1) for prompt Ïc production as a function of J/ÏpT in pp collisions at 7 TeV, using 2011 data collected by CMS experiment. The total integrated luminosity corresponds to 4.62fbâ1. The measurement is performed by reconstructing the Ïc radiative decays to J/Ï+γ, where J/Ï decays into two muons. The photons are reconstructed through their conversions into electron-positron pairs in the tracker. The results are compared with two theory predictions, NLO NRQCD and kT factorization models.
