A study of inelastic hadron-nucleus interactions at 50 and 400 GeV

Some results on multipilcity, mean normalized multiplicity, and pseudorapidity distributions of shower particles produced in pion-nucleus and proton-nucleus collisions at 50 and 400 GeV are presented and discussed. From the study of the pseudorapidity distributions, it is found that the projectile fragmentation is mass independent and the target fragmentation depends upon the target size. The effect of nulcear mass on the forward-backward asymmetry is also examined by using the grey particle multiplicity data. Upon using the additive quark model, a new kind of nuclear scaling is observed between Rsub(A4), in terms of created charged particles and (νsup('))sub(hA)
