One of the computational bottlenecks in state-of-the-art QCD NNLO calculations matched to resummation is the computation of the non-singular contributions to the spectrum of the given resolution variable (for example, the transverse momentum $q_T$ of the color singlet).
While we have a vast set of tools for computing and resumming the singular contributions, the non-singular ones are still...
A crucial step in the investigation of subleading-power corrections is the process-dependent matching from QCD onto SCET$_{\rm II}$. In this matching, one often first performs the hard matching to SCET$_{\rm I}$ and in a second step matches onto SCET$_{\rm II}$.
However, the matching from SCET$_{\rm I}$ to SCET$_{\rm II}$ is process-independent, and thus lends itself to a systematic...
