Abstract
We compare the dispersion of the charges in a central rapidity
box according
to the dual parton model with the predictions of statistical
models. Significant
deviations are found in heavy ion collisions at RHIC and LHC
energies. Hence
the charged particle fluctuations should provide a clear signal
of the dynamics
of heavy ion processes. They should allow one to directly measure
the degree of
thermalization in a quantitative way.
