Abstract
In the hadronic decay mode of a pair of W bosons, →→q, QCD interference effects can mix up the two color singlets q and q, i.e., produce hadrons that cannot be uniquely assigned to either of and . We show that interference is negligible for energetic perturbative gluon emission, and develop models to help us to estimate the nonperturbative effects. The total contribution to the systematic error on the W mass reconstruction may be as large as 40 MeV.
