چکیده
The influence of the Bose-Einstein interference effect on the joint WW hadronic decay is discussed. It is shown that the weight method incorporating this effect into Monte Carlo generators produces in a natural way an excess of average multiplicity as compared to the independent decay of two W bosons. The quantitative results for the average multiplicity and momentum distribution of charged pions, obtained with a simple parametrization of weights compatible with the observed shape of the " Bose-Einstein ratio " , agree well with the existing data.

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, whi...
