説明
CERN-LHC. Measurement of inclusive J/PSI production in P P collisions at a centre-of-mass energy of 7 TeV. Data are presented on rapidity and transverse momentum distributions from a data sample of total integrated luminosity of 3.9 nb-1 in the di-electron channel and 15.6 nb-1 in the di-muon channel, representing 15% of the data collected in the first year of the operation of the LHC. The analysis uses a J/PSI to di-lepton branching ratio of (5.94 +- 0.06)%. The data here are updated according to the erratum which identified problems in the central rapidity range (|yrap|<0.9.
Differential J/PSI cross section from the di-muon channel as a function of transverse momentum, the first error is statistical, the first systematic error is the correlated one, the second is the non-correlated one. The last four columns are the errors (in MUB/GEV) considering a +1 polarization in the Collins-Soper frame, a -1 polarization in the Collins-Soper frame, a +1 polarization in the Helicity frame and a -1 polarization in the Helicity frame, respectively.
