Abstract (data abstract)
CERN-LHC. Measurements of the transverse momentum spectra of charged particles produced in Lead-Lead nuclei collisions at a centre-of-mass energy per nucleon of 2.76 TeV. The measurements use data sets collected in 2010 and 2011 with respective integrated luminosities of 7 mub-1 and 150 mub-1, covering the PT range up to 100 GeV. A reference measurement uses proton-proton data at centre-of-mass energy 2.76 TeV collected in 2011 with integrated luminosity 230 nb-1. Particle yields and invariant differential spectra are presented in a variety of centrality ranges from 0-90%, together with the nuclear modification factor RAA and the TAA-scaled ratios between central and peripheral centrality regions.
