The A-scaling of the multiplicity distributions of π, K and $$\bar P$$ interactions with nuclei at 40 GeV/c.

The multiplicity distributions of charged particles produced from π, K and $$\bar p$$ interactions with the nuclei Li, C, S, Cu, CsI, Pb at 40 GeV/c were studied. It was found that the linear relation D=a〈n〉+b is satisfied for the distributions of different kinds of secondary particles including knocked out protons. Consequently, the use of the scaling variable z′=(an+b)/(a〈n〉+b) ensures the scaling of the distributions with respect to the mass number A at least up to the second moment. [ABSTRACT FROM AUTHOR]
