Hadron production in a fireball radiation model for electron-positron collisions

A model of fireballs radiated ine ⁺ e ^? collisions and radiating in turn other fireballs (i.e. hadrons) is shown to describe well the large bulk of particle production (multiplicities, inclusive distributions, fractions as functions of momenta). One adjustable parameter is used for each kind of hadron emitted (minus an overall constraint). When considered as a process in the mean, the scheme is shown to be equivalent to a sequential decay where the only assumption made is that at each step a particle is emitted with an energy proportional to that of the decaying parent. The consequences of this scheme are investigated and good agreement with the data is obtained.
