Abstract (data abstract)
CERN-LHC. Measurement of inclusive J/PSI production in Lead-Lead collisions at a nucleon-nucleon centre-of-mass energy of 2.76 TeV using data collected during 2010 having integrated luminosity ~ 3 mub-1. The data cover the transverse momentum range > 0 and rapidity from 2.5 to 4.0. Tables of the nuclear modification factor, RAA, are presented both as functions of the centrality of the collision and its associated Number of particles, Npart, as well as in two rapidity and transverse momentum ranges.
