Abstract：
We study the different properties of the two jet like events in e⁺e^－→Z⁰→hadrons under different color connections with the aid of the event generator JETSET. We find that the two kinds of colour connections at the interface of perturbative and nonperturbative QCD, i.e., colour neutral flow and colour separate singlet, lead to significant differences for some observables in the final states. Therefore, the measurements of these observables can be used to distinguish these two kinds of colour connections.
