COLOR INTERFERENCE AND CONFINEMENT EFFECTS IN W-PAIR PRODUCTION

In the reaction e(+)e(-) --> W+W- -->(q(1) ($) over bar q(2)) (Q(1) ($ ) over bar Q(2)) we expect that normally the colour singlet systems (q (1) ($) over bar q(2)) and (Q(1) ($) over bar Q(2)) hadronize independ ently into two hadron chains or strings. However also the pairs (q(1) ($) over bar Q(2)) and (Q(1) ($) over bar q(2)) form colour singlets w ith probability 1/N-c(2) = 1/9. This probability could be further enha nced 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 int eresting information about the vacuum structure. In this paper we disc uss a possible experimental signal for recoupled events and show that such events can be identified also when the effect of gluon emission b efore the recoupling is taken into account.
