The confinement transition from the quark and gluon degrees of freedom appropriate in perturbation theory to hadrons observed by real world experiments is poorly understood. In this strongly interacting regime we presently rely on models, which varying reflect possible scenarios for QCD dynamics. Because absence beam target remnants, clean experimental conditions high event rates, annihilation at provides a unique laboratory, both experimentally theoretically, study parton hadronization....
