Abstract

Two measurements are presented of estimators sensitive to the Colour Reconnection effect in W⁺W^– events at LEP2. The results are compared with various phenomenological Monte Carlo implementations of the effect. A feasibility study is performed to reduce the total uncertainty in the direct m_W measurement at LEP2 by use of the inferred information about the Colour Reconnection effect.
