摘要
A new kind of morphological variables and several multivariate analysis methods are used to separate between four classes of events produced at LEP2: the events with 2 jets, 3 jets, 4 jets and those having a more abundant jet topology (n jets, n > 4). The efficiencies and purities achieved with the optimized neural network are in average 1 to 8 % higher than those obtained with the other techniques.
