Raw primary anti-proton to proton ratio in p-Pb collisions at 5.02 TeV in Monte Carlo simulations.

Detail description

Black points show the results from full-scale Geant4 ALICE simulations (LHC19b1 production), green points correspond to the results from simple Geant4 model. The results of variations of elastic interaction cross-section with simple Geant4 model are shown in blue. For this, the deviations of results due to variation of proton and anti-proton elastic cross-sections (each by ±20%) are added in quadrature.
