Fiducial $q_T$ resummation of color-singlet processes at N$^3$LL+NNLO
We present a framework for $q_T$ resummation at N<sup>3</sup>LL+NNLO accuracy for arbitrary color-singlet processes based on a factorization theorem in SCET. Our implementation CuTe-MCFM is fully differential in the Born kinematics and matches to large-$q_T$ fixed-order predictions at relative order $α^2_s$. It provides an efficient way to estimate uncertainties from fixed-order truncation, resummation, and parton distribution functions. In addition to W<sup>±</sup>, Z and H production, also the diboson processes $\gamma\gamma$, Z$\gamma$, ZH and W<sup>±</sup>H are available, including decays. We discuss and exemplify the framework with several direct comparisons to experimental measurements as well as inclusive benchmark results. In particular, we present novel results for $\gamma\gamma$ and Z$\gamma\gamma$ at N<sup>3</sup>LL+NNLO and discuss in detail the power corrections induced by photon isolation requirements.
