J/psi and Upsilon Production in 7 TeV Proton-Proton Collisions
We present a measurement of the differential J/psi cross section and the ratio of prompt to non-prompt J/psis in 7 TeV proton-proton collisions. We find that the dependence of the cross section on J/psi pT and rapidity is well predicted by Pythia + NRQCD contributions. However the overall normalizat...

| Sumario: | We present a measurement of the differential J/psi cross section and the ratio of prompt to non-prompt J/psis in 7 TeV proton-proton collisions. We find that the dependence of the cross section on J/psi pT and rapidity is well predicted by Pythia + NRQCD contributions. However the overall normalization is found to be almost an order of magnitude lower. The ratio measurement agrees well with theoretical expectations. |
