Using Two-jet Events to Understand Hadronization

: 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 \\Gamma experiments at the Z 0 resonance, it is possible to impose strong two-jet cuts on the data without loosing 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. 1 e-mail patrik@thep.lu.se 2 e-mail gosta@thep.lu.se 1 Introduction High energy reactions like e + e \\Gamma ! hadrons are usually described in terms of two phases, an initial hard perturbative phase formulated as a parton cascade followed by a soft nonperturbative hadronization phase, for which phenomenological models are needed.
