Forward particle production in pp interactions triggered by a 30/sup 0/ pion of momentum exceeding 5 GeV/c has been studied at c.m. energy of 63 GeV. Quantum-chromodynamic model calculations show that in a majority of such interactions the incident proton loses a valence quark. Results indicate that hadronization of diquarks in primarily a recombination process leading to the formation of a high-x baryon.
