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 in the di-electron channel as a function of the relative charged particle multiplicity density (dN_(ch)/deta)/.
