摘要：

A probabilistic approach is formulated to study the behaviour of the incident hadron quark flavours in the fragmentation process of high energy protons in low pT reactions. Analysis of available data on pp collisions, mainly on hyperon and antibaryon multiplicities, leads to estimates of the probabilities for the different ways in which the incident valence quarks recombine into final hadrons. We find that all three incident quarks emerge in one and the same outgoing nucleon (or nucleon resonance) with probability A3=0.35-0.4, that two of them emerge in one baryon and the third in another hadron (mostly a meson or meson resonance) with probability A2=0.6-0.5, and that they emerge in three distinct hadrons (mostly mesons or meson resonances) with probability A1=0.05-0.1. We find good support for a very simple probabilistic picture of the fragmentation process. © 1979 Springer-Verlag.
