Abstract: (Springer)
In the reactione+e− →W+W− → () () we expect that normally the colour singlet systems () and () hadronize independently into two hadron chains or strings. However also the pairs () and () form colour singlets with probability 1/Nc2=1/9. This probability could be further enhanced by gluon exchange. We therefore expect that the hadronization can give “recoupled” colour strings between these quark-antiquark pairs with some small probability, and a study of this effect will give interesting information about the vacuum structure. In this paper we discuss a possible experimental signal for recoupled events and show that such events can be identified also when the effect of gluon emission before the recoupling is taken into account.- electron positron: annihilation
