Abstract

We present an analysis of minimum bias events from proton-proton collisions at\(\sqrt s = 7GeV\) in the CERN ISR. We remove the effects of both the leading protons and compare theB=0 mesonic residue of the events to the hadronic events of similar energy produced ine + e collisions. This comparison is presented in terms of the standard jet-type analyses involving quantities such as sphericity and aplanarity. We find significant differences between these data and the data frome + e annihilations. The data of this experiment are consistent with the predictions of a longitudinal phase space model.
