摘要：We studied the statistical hadronization model in its full microcanonical formulation enforcing the maximal set of conservation laws: energy-momentum, angular momentum, parity, C-parity, isospin and abelian charges. The microcanonical weight (proportional to the probability) of an asymptotic channel, has been calculated in a eld theory framework in order to account for relativistic effects due to the nite cluster's volume. A purposely devised Monte-Carlo method which allows to calculate efciently the channel weight has been set up. A preliminary comparison of the model with measured exclusive rates in low energy (ps =2:1 GeV and 2:4 GeV) e+e􀀀 collisions and with branching ratios of some heavy resonance is shown.
