Can the fluctuations in head-on ultra-relativistic nuclear collisions be large?

We apply the Low-nussinov model of hadron-hadron collisions to nucleus-nucleus collisions. We show that fluctuations in the multiplicity are larger than those for models which assume that the nucleons interact incoherently. The dependence of the total multiplicity onA is difficult to estimate. String formation and breaking is discussed using classical chromodynamic equations to describe the gluon fields. These equations display amusing collective phenomena.
