Abstract
We study a string fragmentation model in which the probability distribution for the locations of the vertices is parametrized explicitly in terms of their space-time coordinates measured from the point of the onset of separation of the quark and the antiquark. An iterative procedure is presented to fragment a finite-mass string into hadrons. We apply the model to calculate the rapidity distribution of the produced hadrons, which is found to give a good fit to the experimental data for annihilation at 29 GeV. From the parameters characterizing the probability distribution of the vertices, we determine the average hadron formation time in the fragmentation of the string.
