COMPARISON OF THE MULTIPERIPHERAL MODEL WITH INCLUSIVE DATA IN K$sup +$p AND $pi$$sup -$p REACTIONS.

Abstract: The pr~dictions of the inultiperipheral model are compared to inclusive data in K+ P and IT P re,!:ctions, We compare with topological \\ longitudinal momentum distributions, double, differential distributions, m~ltiplicity cross-sections, IT+ /ITratio, asymmetry characteristics, isotropy in the cm, and Regge behavior near the kinematical limit. The agreement is reasonably good. We discuss the relation of this work to earlier work on the multi-Regge model, to results of other models, and to the results obtained by other types of approaches to \\ the inclusive analysis. _2 1. INTRODUC TION h I 'h\" I . (1, 2) f t' During t east two years t e mc USlve type 0 reac lOn a + b -+ c .j. anything has become a popular means of studying high energy collisions. Two different approaches to this study can perhap~ be distinguished. On the one hand, detailed studies have been made of the momentum , distribution of particle\" c\" in the momentum regions.gear the kine, /\\ matical limit. For example, comparisons of a given' reaction (e. g. ' (3) , IT + p'\" IT + anything for slow IT in the lab. ) at several energIes have been made to test the Yang conjecture(2) of limiting distributions. Comparisons of the IT distribution of proton targets with different ' incident particles have been made(4) to test the factorization hypothesis(5). Finally, st.udies of a singte reaction at a,single energy have been ,made to test the quantitative predictions of the Regge limit near the kinematical boundary( 6). The advantage of this type of approach is that by examining this momentum range in such detail with these va.rious methods, one can perhaps obtain insight into the precise character, of the production process. H'Owever, the scope of the knowledge is limited for example, little is said about the distribution at PL 0, or about its dependence on prong number, or about correlations between the spectra of different types of secondaries (for example, in a p p reaction the relation between fast produced IT spectra and inelastic p spectra). On the other hand, various dynamical models have been proposed that describe the spectra over the entire momentum_range. For example, we list: (a) the multiperipheral model in the exclusive form of ABFST(7), Chew and Pignotti(8), and CLA(9); and in the inclusive form of Caneschi and Pignotti(10); (b) the thermodynamical model
