Centrality dependence of the nulcear modification factor of charged pions as a function of transverse momentum. Results for Pb-Pb collisions at 5.02 TeV are compared with those at 2.76 TeV. The statistical and systematic uncertainties are shown as error bars and boxes around the data points, respectively.
Detail description
- For Pb-Pb collisions we have used data from the period LHC15o combining the information of the detectors: ITS, TPC, TOF and HMPID.
- The nulcear modification factor was computed using the pp reference which was interpolated using the data of pp collisions at 7 and at 2.76 TeV. The details of the analysis can be found here: https://alice-notes.web.cern.ch/node/428
- The T_AA values for Pb-Pb collisions at 5.02 TeV were taken from this ALICE public note: https://cds.cern.ch/record/2118084/files/ALICE_public_note-2015-008.pdf
- The published Pb-Pb results at 2.76 TeV were taken from: Phys.Rev. C93 (2016) no.3, 034913
