Abstract
We measure the ratio of cross section times branching fraction, Rp=σχc2B(χc2→J/ψγ)/σχc1B(χc1→J/ψγ), in 1.1  fb-1 of pp̅ collisions at √s=1.96   TeV. This measurement covers the kinematic range pT(J/ψ)>4.0  GeV/c, |η(J/ψ)<1.0, and pT(γ)>1.0  GeV/c. For events due to prompt processes, we find Rp=0.395±0.016(stat)±0.015(syst). This result represents a significant improvement in precision over previous measurements of prompt χc1,2 hadro production.
