Topological isolation of the deep inelastic QED Compton scattering
The NA14 photoproduction experiment, carried out at the CERN SPS, has measured the inclusive cross section of events with a prompt photon at high p T in the final state. Here we present a study of the topology of the final state of these events. The topology differs from that observed for events wit...
