We present compact analytic formulas that describe the decay of colorless\nparticles to both q q and gg final states through\nnext-to-next-to-leading order in perturbative QCD in the context of the nested\nsoft-collinear subtraction scheme. In addition to their relevance for the\ndescription of decays like V \→ q q', V= Z,W, H \→ b b and H\n\→ gg, these results provide an important building block for calculating NNLO\nQCD corrections to arbitrary processes at colliders within the nested\nsoft-collinear subtraction scheme.\n
