摘要：

We present the next-to-leading order calculation of two four-jet event shape variables, the D parameter, and acoplanarity differential distributions. We find large, more than 100% radiative corrections. The theoretical prediction for the D parameter is compared to L3 data obtained at the Z(0) peak and corrected to hadron level.
