The production of high transverse energy events in 400 GeV/c pp collisions triggered with a full azimuthal, large solid angle calorimeter is studied. A detailed comparison is made between the experimental data and a QCD Monte-Carlo which includes initial and final state gluon bremsstrahlung. Results on cross sections, energy flows, and event structures are presented for two different types of geometrically unbiased triggers. The characteristics of two and three jet events in the data and Monte-Carlo are also compared. We find that gluon bremsstrahlung effects as implemented in the Field-Fox-Wolfram Monte-Carlo are not sufficient to describe many features of both jetlike and non-jetlike events.
