Description

In this talk I will present the calculation of the next-to-next-to-leading order (NNLO) correction to four-jet production at electron-positron colliders. I will discuss the details of the calculation, which is performed with the antenna subtraction technique relying on recent developments aimed at an efficient numerical implementation, and present precise phenomenological predictions for the four-jet rate.
