Proton–Antiproton Production Asymmetry in Heavy-Ion and pp Collisions at LHC, Simulation in AliRoot Framework

One of the phenomena to be studied on the LHC is the proton–anti- proton asymmetry in heavy-ion and pp collisions. We will be able to study proton stopping and their spectra in plane perpendicular to the beam axis. Measurement of this observable will be possible with the ALICE detector at energies up to 14 TeV in pp and 5.5 ATeV in Pb–Pb collisions. Predictions of the value of proton–antiproton yields asymmetry can be made.
