Multiple correlations and high-transverse-momentum jets in 147-GeV/c -p interactions

We examine multiparticle correlations in a -p experiment at 147 GeV/c performed by the Proportional Hybrid System Consortium. The major aim of this paper is to demonstrate the existence of clusters in our data. We use different statistical algorithms to assemble into clusters the particles in each event which are associated by virtue of small relative angles. We find that these clusters are stable against different choices of metric and/or algorithm, and reproduce the effects previously observed in the data corresponding to clusters. Some of these clusters have properties similar to high-pT jets. A detailed study of these jetlike clusters is described, and comparisons with some counter experiments are discussed. © 1981 The American Physical Society.
