QCD corrections to e<sup>+</sup>e<sup>-</sup>โ four jets
We report on the next-to-leading-order QCD calculation for e+e-โ four jets. We explain some modern techniques which have been used to calculate the one-loop amplitudes efficiently. We further report on the general purpose numerical program `MERCUTIO', which can be used to calculate any infrared-safe four-jet quantity in electron-positron annihilation at โฆ
