摘要：

We present a partonic Monte Carlo event generator that can be used for calculating the group independent kinematical functions of any infrared safe four-jet observable at next-to-leading order accuracy. As an example, we calculate the differential distribution of the Pi(1) and Pi(4) Fox-Wolfram moments. We find large K factors (K > 2). The effect of the radiative correction is to increase the overall normalization, but not to reduce the renormalization scale dependence significantly.
