    "abstract": "Event-by-event multiplicity fluctuations in nucleus-nucleus collisions are\nstudied within the HSD and UrQMD transport models. The scaled variances of\nnegative, positive, and all charged hadrons in Pb+Pb at 158 AGeV are analyzed\nin comparison to the data from the NA49 Collaboration. We find a dominant role\nof the fluctuations in the nucleon participant number for the final hadron\nmultiplicity fluctuations. This fact can be used to check different scenarios\nof nucleus-nucleus collisions by measuring the final multiplicity fluctuations\nas a function of collision centrality. The analysis reveals surprising effects\nin the recent NA49 data which indicate a rather strong mixing of the projectile\nand target hadron production sources even in peripheral collisions.",
