Target mass dependence of multiplicity distribution of particles produced in hadron-nucleus interactions is exhibited by a new kind of empirical relation through the study of the mean number of wounded quarks. Scaling in proton-nucleus as well as proton-proton collisions is studied and is extrapolated to see its applicability to the data at the highest energy available.

An attempt has been made to investigate the multiplicity distributions of grey, black, shower, and heavy tracks, the dispersions of their distributions, intercorrelations between them, the dependence of the mean normalized multiplicity on the target mass and energy, etc., in hadron–nucleus interactions at 24, 50, and 400 GeV incident energies. The results obtained in the study reveal that the behaviour of the multiplicity distribution is independent of the nature and energy of the impinging hadron. Furthermore, on redefining the mean normalized multiplicity, it is found to be not only energy independent but also projectile independent, suggesting a new kind of scaling in particle–nucleus interactions.

The Impact

The present paper deals with the interactions of 22 Ne and 28 Si nuclei at (4.1–4.5)A GeV /c with emulsion. Some characteristics of the compound multiplicity nc given by the sum of the number of shower particles ns and grey particles ng have been investigated. The present experimental data are compared with the corresponding ones calculated according to modified cascade evaporation model (MCEM). The results reveal that the compound multiplicity distributions for these two reactions are consistent with the corresponding ones of MCEM data. It can also be seen that the peak of these distributions shifts towards a higher value of nc with increasing projectile mass. It may further be seen that the compound multiplicity distributions becomes broader with increasing target size and its width increases with the size of the projectile nucleus. In addition, it has been found that the MCEM can describe the compound multiplicity characteristics of the different projectile, target and the correlation between different emitted particles. The values of average compound multiplicity increase with increasing mass of the projectile. Furthermore, it is observed that while the value of 〈nc〉 depends on the mass number of the projectile Ap and the target mass number At, the value of the ratio 〈nc〉/D(nc) seems to be independent of Ap and At. The impact parameter is found to affect the shape of the compound multiplicity distribution. Finally, the dependence of the average compound multiplicity on the numbers of grey and black particles, and the sum of them, is obvious. The values of the slope have been found to be independent of the projectile nucleus.
