WW decays and Bose-Einstein correlations

Abstract

Various methods of implementing the Bose-Einstein effect into Monte Carlo generators, especially for the process e^+ e^- > W^+ W^-, are briefly reviewed and their predictions for the W mass shifts are compared. The weight methods, which yield very similar predictions independent on the detailed prescription for weights, are discussed in more detail. In particular, we advocate a new method, which seems to be practical and reasonably well justified theoretically.
