Jet Physics at Two-Loop Accuracy

Abstract

Current phenomenological studies of jet observables at colliders are clearly limited by the theoretical uncertainties inherent in the next-to-leading order QCD description. We discuss the recent progress made towards the calculation of QCD corrections to jet observables at the next-to-next-to-leading order in QCD and highlight future perspectives and yet open issues.
