Transverse-energy distribution in proton–nucleus collisions at high energy

Abstract

Based on the model of nuclear-collision geometry, the independent N–N collision picture and participant contribution picture are used to describe the transverse-energy distribution in p–A collisions at high energy. In the independent N–N collision picture, the energy loss of leading proton in each p–N collision is considered. The calculated results are in agreement with the experimental data of p–Al, p–Cu, and p–U collisions at 200 GeV/c. PACS Nos.: 13.85-t, 13.85Hd, 25.75-q
