Abstract Energy-flow distributions for charged hadrons from interactions of photons, pions and kaons on hydrogen are presented as functions of Σp T 2 in the event plane. Data cover the range 0.0〈Σp T in 2 〈10.0(GeV/c)2 and 0.0〈x F 〈1.0 for beam momenta from 65 to 170 GeV/c. The comparisons between photon-and hadron-induced data show an excess of events with larger Σp T in 2 for the photon-induced data. Using the hadron-induced data to parameterise the hadronic behaviour of the photon, the differences between cross sections are used to measure the contribution of the point-like photon interactions. Quantitative calculations of the point-like photon interactions using the Lund Monte-Carlo program LUCIFER, based on QCD, are in agreement with the data.
