High transverse energy and high transverse momentum events in anti p p and pp interactions at the CERN intersecting storage rings

A comparison between anti p p and pp interactions at ..sqrt..s = 52.7 GeV is presented for a total neutral transverse energy (E/sub T//sup 0/) trigger and for a high transverse momentum (p/sub T/) neutral cluster trigger. The rate of production of events in the range 6 < E/sub T//sup 0/ < 20 GeV is observed to be 10% higher in anti p p 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 anti p p collisions. The ratio of the production cross section for single neutral clusters in anti p p and pp interactions in the range 1.25 < p/sub T/ < 10 GeV/c does not significantly differ from unity.
