Description
We modify a previously developed multi-string model for particle production to include the primordial transverse momentum of the partons in the incoming hadrons. Rapidity spectra, correlations and multiplicity distributions are unsensitive to the modification. The average transverse momentum of secondaries is found to increase with multiplicity, as observed at the SPS collider. However, a rather large parton transverse momentum (1.1-1.4 GeV) is required.
