Abstract

Prompt production of charmonium Χ_c0, Χ_c1 and Χ_c2 mesons is studied using proton-proton collisions at the LHC at a centre-of-mass energy of √s = 7TeV. The Χ_c 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 Χ_c1 and Χ_c2 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 Χ_c0 meson production at a high-energy hadron collider is also presented.

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.
