Protons and anti-protons interactions in ATLAS Inner Detector (FTFP_BERT)

Comparisons of fractions of non-interacting tracks from identified protons and anti-protons from Λ-decay to two G4 physics lists. The data and MC are plotted as a function of pT. The purity of the proton/anti-proton tracks is already before background subtraction (based on side-bands around the Λ mass).
