On the Origin of the Multiplicity Fluctuations in High Energy Heavy Ion Collisions
G. V. Danilov, E. V. Shuryak
Abstract
Multiplicity fluctuations in heavy ion collisions obtain comparable contributions both from initial stage of the collisions, and from final stage interaction. We calculate the former component, using the ``wounded nucleon'' model and standard assumptions about nuclei and NN cross section. Combining it with the second one, calculated previously by Stephanov,Rajagopal and Shuryak, ref.2, we obtain good quantitative description of experimental data (ref.3) from NA49 collaboration at CERN on central PbPb collisions.
