Abstract
The dynamical string-parton model for relativistic heavy-ion collisions is generalized to include particle identification of the final-state hadrons b y phenomenologically quantizing the masses of the classical strings which r esult from string breaking. General features of the Nambu-Goto strings are used to motivate a model that identifies a mass window near the physical ma ss of a meson, and does not allow the string to decay further if its mass f alls within the window. Data from e(+)e(-) collisions in the region root s = 10 to 30 GeV are well reproduced by this model.
