Abstract

The prompt production of charmonium chi_c and J/Psi states is studied in proton–proton collisions at a centre-of-mass energy of sqrt(s)=7 TeV at the Large Hadron Collider. The chi_c and J/Psi mesons are identified through their decays chi_c -> J/Psi gamma and J/Psi-> mu+mu- using 36 pb−1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for chi_c and J/Psi, sigma(chi_c -> J/Psi gamma)/sigma(J/Psi), is determined as a function of the J/Psi transverse momentum in the range 2
