Influence of the collision centrality upon negative particle production indC, αC and CC interactions at 4.2 GeV/c per nucleon
1990
The influence of collision centrality upon spectra of negative particles produced indC, αC and CC interactions at 4.2 GeV/c per nucleon is studied. The netcharge of secondary particles is used as a measure of collision centrality. Comparison with the nucleon-nucleon collisions and with Dubna intranuclear cascade model is presented. The main features of the momentum, rapidity and angular spectra are compatible with the independent, nucleon-nucleon collision picture. Only in thep T spectra, the observed particle excess, for low and highp T , is inconsistent with this approach. In contrast to the pions, the spectra of protons are more sensitive to the collision centrality.
