Description
The $N$-jettiness slicing has been a successful approach for the calculation of cross sections at next-to-next-to-leading order (NNLO) in perturbative QCD, and has a strong potential for computations at the following order. Recently we derived a compact representation of the renormalized $N$-jettiness soft function free of infrared and collinear divergences through NNLO. The convergence of the $N$-jettiness scheme can be systematically improved by the addition of power corrections, for which there has been significant interest in understanding the subleading power contributions and their importance.
