Measurement of the relative prompt production rate of χ c2 and χ c1 in pp collisions at √s = 7 TeV
A measurement is presented of the relative prompt production rate of χ c2 and χ c1 with 4.6 fb ⁻¹ of data collected by the CMS experiment at the LHC in pp collisions at √s = 7 TeV. The two states are measured via their radiative decays χ c →J/ψ+γ, with the photon converting into an e + e - pair for...
