COMPARATIVE-ANALYSIS OF MULTIPLICITY DISTRIBUTIONS IN INELASTIC PROCESSES FOR DIFFERENT COLLIDING PARTICLES AND NUCLEI

Theoretical prediction of oscillations of cumulant moments of parton m ultiplicity distributions inside a jet supported by experimental data in some multiple production processes asks for analysis of the phenome non for the whole set of available reactions. We have found that the o scillations persist in any kind of processes and increase for particle s with more complicated structure, i.e. in the order of ee, eh, hh, hA , AA. The effect is not strongly dependent on the available phase spac e. Theoretical values of moments for quark and gluon jets up to 5th ra nk are shown. Zeros of the truncated generating function and singulari ties of the total generating function are discussed. (C) 1997 Elsevier Science B.V.
