Particle dependent tracking efficiency of the measurement of charged hadrons in ALICE

The ALICE experiment at the LHC is designed to study the properties of the Quark-Gluon-Plasma (QGP) based on high energy pp, p-Pb and Pb-Pb collisions. Certain properties of these collisions can be studied by measuring the production of charged hadrons. In ALICE charged hadrons are measured with the Time Projection Chamber (TPC) and are corrected for the tracking efficiency of the detector. Here, tracking efficiencies are calculated based on two simulations: A Monte Carlo generator for the particle production and GEANT, to simulate the detector response. As the particle abundances in Monte Carlo simulations differ from the measured yields of identified particles, the composition of the inclusive tracking efficiency has to be tuned. We present a systematic study of the particle dependent tracking efficiency of the measurement of charged hadrons, especially in pp collisions at √(s) = 13 TeV.
