[en] Recent data on the multiplicity distribution of charged particles produced in non-diffractive panti p collision at √s = 540 GeV are presented. A definite change of the normalized multiplicity distribution is observed when compared to lower energy data up to 62 GeV. A significant violation of KNO scaling is also clearly evidenced by the moments of the multiplicity distribution. The analysis of short range two particle correlations gives results for the mean cluster decay multiplicity consistent with previous results from a study of long range forward-backward correlations. The mean cluster is compatible with decaying into 1.5 resonances or directly produced stable particles which contribute in average 1.4 charged secondaries. (orig.)
