Abstract
- The prompt production of charmonium χ c and J/ψ states is studied in proton-proton collisions at a centre-of-mass energy of s=7 TeV at the Large Hadron Collider. The χ c and J/ψ mesons are identified through their decays χ c→J/ψγ and J/ψ→μ +μ - using 36 pb -1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J/ψ, σ(χ c→J/ψγ)/σ(J/ψ), is determined as a function of the J/ψ transverse momentum in the range 2
