摘要：

We calculate the rate for e(+) e(-) annihilation into four jets at next-to-leading order in perturbative QCD, but omitting terms that are suppressed by one or more powers of 1/N-c(2) where N-c is the number of colors. The O(alpha(s)(3)) corrections depend strongly on the jet resolution parameter y(cut) and on the clustering and recombination schemes, and they substantially improve the agreement between theory and data.
