Selected Experimental Results from Heavy-Ion Collisions at LHC
Figure 15
(Color online) (a) Nuclear modification factor of charged hadrons measured by ALICE [26] and CMS [27] experiments at midrapidity for 0–5% most central collisions at TeV. For comparison, shown are the of charged hadrons at midrapidity for 0–5% most central collisions measured by STAR [115] and of at midrapidity for 0–10% most central collisions measured by PHENIX [173] for collisions at GeV. (b) Comparison of nuclear modification factor for charged hadrons versus at midrapidity for minimum bias collisions in collisions at GeV [115] and collisions at TeV [116]. (c) The nuclear modification factor versus for isolated photons in central nucleus-nucleus collisions at GeV [119] and 2.76 TeV [120]. Also shown are the integrated of [121] and bosons [122] at corresponding at LHC energies. Open and shaded boxes represents the systematic uncertainties in the experimental measurements and normalization uncertainties, respectively.
