Abstract

We compute the differential distributions of two three-jet event-shape observables at the next-to-leading order accuracy at fixed values of the DIS kinematic variables. The observable Kout measures the out-of-event-plane momentum. The other observable y3 is the maximum value of the ycut resolution variable for which an event is classified as three-jet event. We also show the dependence of the fixed-order predictions on the renormalization and factorization scales. The radiative corrections are in general large and depend on the value of the DIS kinematic range.
