摘要：
A new signal is proposed for the colour reconnection in the hadronic decay of W+ W- in c(+)c(-) collisions. Using Pythia Monte Carlo it is shown that factorial correlators for W+ and W- without colour reconnection are almost identical to unity, while those for the cases with colour reconnection fall down approximately linearly in the log-log plot. This signal, being based on the factorial correlator, is more sensitive than the ones using only averaged quantities.
