Measurement of the ratio of prompt χ c to J/ψ production in pp collisions at √s=7 TeV

Measurement of the ratio of prompt χ c to J/ψ production in pp collisions at √s=7 TeV

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 i...
