Measurement of the relative prompt production rate of χ c2 and χ c1 in pp collisions at [Formula: see text].

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 [Formula: see text]. The two states are measured via their radiative decays χ c→J/ψ+γ, with the photon converting into an e(+)e(-)...
