A study of high energy hadron–nucleus interactions

Abstract

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.
