    "abstract": "We study the scaled variances of multiplicity fluctuations in nucleus-nucleus\ncollisions at SPS and RHIC energies within the HSD transport model. The HSD\nresults are compared with proton-proton data and with predictions of the\nhadron-resonance gas statistical model. We find that the HSD scaled variances\n$\\omega_i$ for negatively, positively, and all charged hadrons in central\nnucleus-nucleus collisions remain close to the $\\omega_i$ values in\nproton-proton collisions and increase with collision energy as the\ncorresponding multiplicities per participating nucleon. The statistical model\npredicts very different behavior of $\\omega_i$. However, a comparison with\npreliminary NA49 data for the most central Pb+Pb collisions at SPS energies\ndoes not permit to distinguish the HSD and statistical model results. New\nmeasurements of the multiplicity fluctuations in nucleus-nucleus collisions in\na wide energy region with large acceptance are needed to allow for a proper\ndetermination of the underlying dynamics.",
