    "abstract": "The multiplicity fluctuations are studied in the van der Waals excluded\nvolume hadron-resonance gas model. The calculations are done in the grand\ncanonical ensemble within the Boltzmann statistics approximation. The scaled\nvariances for positive, negative and all charged hadrons are calculated along\nthe chemical freeze-out line of nucleus-nucleus collisions at different\ncollision energies. The multiplicity fluctuations are found to be suppressed in\nthe van der Waals gas. The numerical calculations are presented for two values\nof hard-core hadron radius, $r=0.3$ fm and 0.5 fm, as well as for the upper\nlimit of the excluded volume suppression effects.",
