Abstract Large transverse momentum particles in hadron collisions are thought to arise from hard constituent scattering where the scattered constituents manifest themselves as jets of hadrons. Cross-sections for the production of narrow jets have been measured and found to agree with a simple quark-parton model. A recent experiment with broad acceptance, NA5 at CERN, has found cross-sections and event structure at 300 GeV/c incompatible with the simple model. This report presents data on pp and pA collisions at 400 GeV/c also taken with a large acceptance calorimeter. Cross-sections for various aperture sizes, influences on the 'jettiness' of the event, and the anomalous nuclear enhancement are investigated.
