Abstract
We give a detailed description of the multistring model v e n u s for nucleon-nucleus collisions at ultrarelativistic energies. According to the model, color strings are formed as a consequence of color exchange between quarks of colliding nucleons. Sequences of nucleon-nucleon collisions are determined from geometrical considerations. We calculate, among other things, multiplicity distribution for various rapidity intervals for p-p, p-Ar, and p-Xe at 200 GeV, to compare with negative-binomial fits to data.
