LINKING DYNAMICAL AND THERMAL MODELS OF ULTRARELATIVISTIC NUCLEAR-SCATTERING

To analyze ultrarelativistic nuclear interactions, usually either dyna mical models like the string model are employed, or a thermal treatmen t based on hadrons or quarks is applied. String models encounter probl ems due to high string densities; thermal approaches are too simplisti c. considering only average distributions and ignoring fluctuations. W e propose a completely new approach. providing a link between the two treatments, and avoiding their main shortcomings: based on the string model, connected regions of high energy density are identified for sin gle events, such regions being referred to as quark matter droplets. E ach individual droplet hadronizes instantaneously according to the ava ilable,I-body phase space. making use of special Monte Carlo technique s.
