We present a framework for qT resummation at N3LL+NNLO accuracy for arbitrary color-singlet processes based on a factorization theorem in SCET. Our implemen- tation CuTe-MCFM is fully differential in the Born kinematics and matches to large-qT fixed-order predictions at relative order αs2. It provides an efficient way to estimate uncer- tainties from fixed-order truncation, resummation, and parton distribution functions. In addition to W±, Z and H production, also the diboson processes γγ,Zγ,ZH and W±H are available, including decays. We discuss and exemplify the framework with several di- rect comparisons to experimental measurements as well as inclusive benchmark results. In particular, we present novel results for γγ and Zγ at N3LL+NNLO and discuss in detail the power corrections induced by photon isolation requirements.
