Abstract
While the hard phase of the strong interaction is well
described
by perturbative QCD, the soft hadronization phase is less understood.
Benefiting from the high statistics from e+e- experiments at the
resonance, it is possible to impose strong two-jet cuts
on the data without losing the statistical significance. In these
events perturbative activity is suppressed and hadronization effects
can be more prominent. We show that after proper event cuts a set of
observables are sensitive to differences in the hadronization
models. These observables can thus be important tools for a more
detailed study of the hadronization mechanism.
