Abstract

Prompt production of charmonium Χc0, Χc1 and Χc2 mesons is studied using proton-proton collisions at the LHC at a centre-of-mass energy of √s = 7TeV. The Χc mesons are identified through their decay to J/Φ,γ with J/Φ → μ+μ- using photons that converted in the detector. A data sample, corresponding to an integrated luminosity of 1.0 fb-1 collected by the LHCb detector, is used to measure the relative prompt production rate of Χc1 and Χc2 in the rapidity range 2:0 < y < 4:5 as a function of the J/Φ transverse momentum from 3 to 20 GeV=c. First evidence for Χc0 meson production at a high-energy hadron collider is also presented. © SISSA 2013.
