Abstract
Fast forward particles photoproduccd in 20-GeV interactions on a hydrogen target are shown to be preferentially positive, the asymmetry increasing with transverse momentum and Feynman x. Evidence is given that this effect is not due to forward-going target fragments. A model in which production from the photon of a forward-going spectator u is preferred over a u, due to a higher probability for interactions of antiquarks with the proton constituents, is shown to be qualitatively consistent with the data.
