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