Centrality dependence of the nulcear modification factor of charged pions, kaons and (anti)protons as a function of transverse momentum. 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 (For kaons the results from the kink analysis are included).
- 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 were taken from this ALICE public note: https://cds.cern.ch/record/2118084/files/ALICE_public_note-2015-008.pdf
