Abstract

We present our results on multiplicity fluctuations in the framework of the string clustering approach. We compare our results---with and without clustering formation---with CERN Super Proton Synchrotron NA49 data. We find a nonmonotonic behavior of these fluctuations as a function of the collision centrality, which has the same origin as the observed fluctuations of transverse momentum: the correlations between the produced particles because of the cluster formation.
