INC model calculation of (π+, p), ( $$\bar p$$ , p) and (K+, p) spectra in the 1GeV/c range, p) and (K+, p) spectra in the 1GeV/c range

Abstract

The proton inclusive spectra measured with 800MeV/cπ+ beam (BNL) on light nuclei, and the 600MeV/c\(\bar p\) beam (LEAR) on6Li and63Cu have been successfully interpreted in terms of the Intranuclear Cascade (INC) Model. According to the INC model predictions the\(\bar p\) induced reaction results in high pion yield for the light6Li target case. This is attributed to the nonavailability of nucleons to be knocked out by the pions produced following the\(\bar p\) annihilation. While in the case of the heavier63Cu target some of the internally produced pions are subsequently absorbed leading to thermal equilibration of the nuclear medium, resulting in a softer proton spectrum at the high-energy end. Based on the INC model predictions the K+ induced reactions could be studied to search for the «true resonances» beyond 1GeV K+ energy.
