Results of pn and pp multiplicity distributions from pd interactions at 400 GeV/c are presented together with others from 100–300 GeV/c. These, along with the corresponding distributions for pp interactions in a hydrogen bubble chamber were analysed to look into their scaling behaviour. It has been shown that neither the semi-inclusive scaling hypothesis nor the Mueller–Regge approach can explain the behaviour of data at 400 GeV/c. The subtraction of the leading particle did not seem to be effective. The charged multiplicities are shown to have a negative binomial distribution.

A summary of the work carried out at the Institute for High-Energy Physics, Serpukhov, U. S. S. R., on proton-proton interactions at energies between 10 and 70 GeV is given. The experiments comprise studies of small angle elastic scattering, of total cross-sections and of interactions in a hydrogen bubble chamber.

Multiplicity Distributions

We present a study on the charged multiplicity distribution in proton–neutron (pn) interactions at 400 GeV/c from the data on an exposure of a Fermilab 30-in. deuterium bubble chamber to 400 GeV/c protons. The pn and pp distributions were extracted through an empirical model to correct for double scattering in deuterium. The overall average fraction of the double scattered event is 0.128 ± 0.011. The resulting pn and pp multiplicity distributions give average multiplicities of 8.48 ± 0.10 and 8.99 ± 0.12 respectively. The fraction of pd events which occur off the neutron is 0.52 ± 0.02. The extracted pp distribution parameters are compared with those from the hydrogen bubble chamber (HBC) experiments. Distinctive features of extracted pn distribution are discussed.
