Inclusive distribution of protons in nucleus-nucleus collisions at high energy has been studied in both forward and backward regions according to the hard scattering model. It is observed that proton production may occur in two ways: (1) the emitted proton is one of the interacting protons in the nucleus and (2) the proton is emitted from a secondary virtual pion along with an antinucleon. Process (1) is dominant in the interaction BA..-->..px in the region 0 < or = BX/sub F/ < or = 1 when the inclusive cross section shows a rise with X/sub F/ and process (2) is dominant in the region BX/sub F/ > or = 1 with X/sub F/ < or = 1 where the cross section shows a sharp fall with X/sub F/. This feature is found to be in good agreement with experiments. Besides, it is predicted that though there will be approximate scaling (very small change with energy) in the forward region, in the backward region scale breaking will be dominant.
