Monte Carlo calculation of high-energy heavy-ion interactions

摘要: A relativistic Monte Carlo model for high-energy heavy-ion collisions is presented. The interaction process described as a sequence of classical, binary, on-shell baryon-baryon collisions. Pion production taken into account by allowing $\ensuremath{\Delta}$ resonance formation. latter are given definite mass and lifetime larger than the collision time. They are, however, allowed to scatter or disappear with nucleons. results calculations compared experimental inclusive proton pion cross sections two-proton correlations in $^{12}\mathrm{C}$+$^{12}\mathrm{C}$, $^{20}\mathrm{Ne}$+NaF, $^{40}\mathrm{Ar}$+KCl systems at 800 MeV per nucleon. predictions agree fairly well measurements, except low-energy section, which underestimated. relation this feature zero-width spectrum resonances briefly discussed. used separate direct knockout thermal contributions section. Attention drawn fact that these two not unambiguously defined.
