CERN-LHC. Measurement of the production of J/PSI mesons in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data were collected during September 2010 with a total integrated luminosity of 5.2 pb-1 and cover the fiducial range in transverse momentum (PT) from 0 to 14 GeV/c and in rapidity (YRAP) from 2.0 to 4.5. The data are separated into prompt J/PSI production and J/PSI from b-hadron decay, with three assumptions of the polarisation of the J/PSI (none, fully transverse and fully longitudinal).
