NNLO QCD corrections to dijet production at hadron colliders

Abstract

In this talk we present the calculation of next-to-next-to-leading order (NNLO) QCD corrections to dijet production and related observables at hadron colliders in the purely gluonic channel. Results for this channel are obtained keeping all orders of $N_C$ in the colour expansion. We show that the NNLO correction significantly reduces the scale uncertainty compared to next-to-leading order (NLO). We present the NNLO double-differential single jet inclusive cross section where jets are reconstructed using the anti-$k_T$ jet algorithm and show the dependence on the jet resolution parameter $R$.
