Abstract (data abstract)
CERN-LHC. Measurement of the inclusive J/PSI yield as a function of the charged particle pseudorapidity density (DN/DETARAP) in proton-proton collisions at a centre-of-mass energy of 7 TeV. J/PSI particles are detected in two decay modes separately. For di-electron decays the data are collected in the |rapidity| interval < 0.9 with a total integrated luminosity 5.6 nb-1 and for di-muon decays the data cover the rapidity region 2.5 to 4 with total integrated luminosity 7.7 nb-1.
