Abstract (data abstract)
CERN-LHC. Measurement of the relative production rates of CHI/C2 and CHI/C1 mesons in proton-proton collisions at a centre-of-mass energy of 7 TeV from a data sample of intergated luminosity of 4.6 fb-1. The CHI/Cs are measured via their radiative decays to J/PSI + GAMMA with the photon converting to an E+ E- pair in the fiducial region of PT(C=GAMMA)>0.5 GeV/c and |y(J/PSI)/<1.0. Data are given as a function of PT(/J/PSI) from 7 to 25 GeV/c.
