“…But the studies on grey particles may provide some useful information because they are envisaged to be produced during or shortly after the passage of leading hadron and hence are expected to remember a part of the history of the reaction. Grey particles may also be taken as good measure of the number of collisions made by the striking hadron inside the target nucleus [7][8][9][10][11]. When a primary particle collides with a target nucleus, the secondary particles produced are shower ( ), grey ( ), and black ( ).…”

We report some results on the compound multiplicity distribution at 340 GeV/c − nucleus interactions. Compound multiplicity distribution is found to depend on the target size and the distribution becomes broader. The peak of the distribution shifts towards higher values of the compound particle multiplicity. Mean compound multiplicity is found to vary linearly with grey, heavy, and shower particle multiplicity. Correlations between different particle multiplicities have been studied in detail. Dispersion of compound multiplicity distributions and its ratio with the mean value is observed to obey a linear relationship with different particle multiplicities except for shower particles where dispersion is almost independent of shower particles. Mean normalized multiplicity has also been studied in terms of created charged particles.

“…The present study extends these measurements to p+C interactions. The use of the isoscalar, light 12 C nucleus has several motivations. Firstly, it allows inspection of the evolution from elementary to nuclear collisions for a small number of intranuclear projectile interactions as compared to the high-statistics data sets on the heavy 208 Pb nucleus from the NA49 experiment [2].…”

The production of charged pions in minimum bias p+C interactions is studied using a sample of 377 000 inelastic events obtained with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. The data cover a phase space area ranging from 0 to 1.8 GeV/c in transverse momentum and from -0.1 to 0.5 in Feynman x. Inclusive invariant cross sections are given on a grid of 270 bins per charge thus offering for the first time a dense coverage of the projectile hemisphere and of the cross-over region into the target fragmentation zone.

Abstract. Intranuclear cascade model calculations are carried out on the recent measurements (WA80 Collaborations) for the multiplicity, energy and angular distributions of singly charged target fragments of energy in the range 30 < E < 400 MeV (the so-called grey particles) produced in proton-nucleus interactions at 200 GeV/c. It is shown that these distributions are reasonably well understood in terms of the intranuclear cascade model which considers that grey particles are only produced in the first two generations of the cascade. The obtained distributions, mean values and target mass dependence are more consistent with the experimental data than other models using Monte Carlo Simulations. PACS:26.70.
