Inclusive Reactions: Models of Multi‐Particle Production

Abstract

Nodel independent predictions such as Feynman scaling and the hypothesis of limiting fragmentation (HLF) for multi-particle production are reviewed . The thermodynamic model and the multi-Reggc model and their description of inclusive spectra are outlined and the connection of both models is discussed with special emphasis on the predictions of these models fulfilling Feynman scaling and HLF . Various possibilities for data presentation are discussed as well as tests are proposed to distinguish between different models .

Universal transition curve in pseudorapidity distribution

“…Many models for hadron-hadron col-lisions developed in the 1970's [36][37][38][39][40] also had this type of dn / d. As will be shortly shown, this Woods-Saxon form is not compatible with the transition region universality and hence it is unlikely that this is the right form of dn / d. Nevertheless we feel that it is worth considering the Woods-Saxon form here because it gives an example of slowly changing (as opposed to universal) limiting fragmentation curve.…”
