description This report depicts the work I have done during my 8 week period as a summer student. ALICE officially uses GEANT3 but needs to switch to Geant4 as it is advantageous. During this study, we observed that GEANT3 describes the experimental data more accurately at higher momentum in certain regions of the energy loss in the TPC whereas Geant4 describes the data more accurately at lower momentum. We also observed that Geant4 has a higher tracking efficiency for the proton, pion, kaon and antiproton at low momentum in the TPC and TOF. At mid-momentum, GEANT3 and Geant4 is observed to have the same efficiency. However, further study is needed.
