Abstract：
The negative correlation in W⁺W^－ hadronic decay, which has recently been proposed as a possible signal for the colour reconnection in these proceses, is studied in some detail by using the random cascadingα-model. The effect of colour reconnection is modeled by the particle exchange between two final state systems forming from two W's. The negative correlation given by Pythia event generator is recovered in this way, providing a physical picture for this effect.
