Effects of in-medium cross-sections and optical potential on thermal-source formation in p+Au reactions at 6.2-14.6 GeV/c

Effects of in-medium cross-sections and of optical potential on pre-equilibrium emission and on formation of a thermal source are investigated by comparing the results of transport simulations with experimental results from the p+197Au reaction at 6.2-14.6 GeV/c. The employed transport model includes light composite-particle production and allows for inclusion of in-medium †Present address: Los Alamos National Laboratory, Los Alamos, NM 87545 ‡Present address: Rush Presbyterian St. Lukes Medical Center, Chicago, IL 60612 §Present address: Epsilon Inc., Dallas TX 75240 ∗∗Present address: LPC Caen, 6 Boulevard Maréchal Juin, 14050 Caen Cedex, France ††Present address: Los Alamos National Laboratory, Los Alamos, NM 87545 ‡‡Present address: Lawrence Berkeley National Laboratory, Berkeley, CA 94720 §§Present address: Department of Physics, Cambridge University, United Kingdom
