Abstract
Feynmanx distributions for the inclusive reactionsP+P→hadron+anything at 360 GeV/c are analyzed in terms of a quark-diquark fragmentation model. The proton is assumed to be composed either of a quark and a diquark or of three independent quarks. The model tested includes a hadronization part for which we use the Field-Feynman and LUND fragmentation functions. The model with diquarks gives a better description of our experimental data; in particular forP+P→Λ 0+anything, the model without diquarks fails to reproduce the data.
