Description
Interactions of 40 GeV/c π-, K- and anti p on Li, C, S, Cu, CsI and Pb were studied with the RISK-streamer chamber spectrometer. We present multiplicities of negatively charged particles, as well as of protons, and the correlations between them. The normalized mean multiplicity of negative particles, R-, depends on anti ν, the average number of inelastic collisions as R-=(0.73+-0.04)+(0.34+-0.02)anti ν. The dependence of the normalized dispersion of negative particles, D-/, on the number of protons favours independent collision models and contradicts the coherent tube picture. The excess of fast positive particles behaves as Asup(0.4) and shows, for the heavier nuclei, a clear correlation with identified protons. (orig.)
