<dt>Descripción</dt>
<dd>A model of fireballs radiated in &lt;math&gt;\operatorname e^+e^-&lt;/math&gt; 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 and the proportionality factor turns out to be, numerically, nothing but the running coupling constant of QCD. The consequences of this scheme are investigated.</dd>
