Abstract
We study ultra-relativistic heavy-ion collisions using, as far as possible, known physics and simple assumptions. One focus is on the measurable effects of rescattering of produced particles in the colliding nuclei. Two models for proton-nucleus collisions are presented, one built from independent hadron-hadron collisions, the other based on the Lund model. We use them to study various assumptions about rescattering.
Another focus is on fluctuations of global observables. We find a general formula for fluctuations in independent-collision models and show that its predictions are inconsistent with experimental data. We discuss possible explanations of the data. The fluctuations in our previously presented models are calculated and and examined in the light of that discussion. Finally we give a method for comparing calculated fluctuations to experimental
results.
