Abstract

A comparison between pp and pp interactions at √s = 52.7 GeV is presented for a total neutral transverse energy (ETo) trigger and for a high transverse momentum (pT) neutral cluster trigger. The rate of production of events in the range 6<ETo<20 GeV is observed to be 10% higher in pp collisions than in pp collisions. A study of the structure of the events shows this excess to be due to more isotropic events being produced in pp collisions. The ratio of the production cross section for single neutral clusters in pp and pp interactions in the range 1.25<pT<10 GeV/c does not significantly differ from unity.
