Abstract

Measurements are reported of inclusive production of pi-0-mesons in the beam fragmentation region in gamma-p, pi-p and Kp collisions. Results include the ratio of pi-0 production in Kp and pi-p collisions, showing reduced production from fragmentation of the K-meson, and the ratio of pi-0 production in photon and hadron collisions which shows agreement with modified Vector Meson Dominance at low p(T), and departures at higher p(T) signalling the onset of direct photon reactions. The pattern of departure from Feynman scaling at high p(T) points to a contribution of hard parton-parton collisions in both gamma-p and pi-p collisions.
