Description
We compute the fully differential decay rate of the standard model
Higgs boson to a b-quark pair at NNLO accuracy. We use a general
subtraction scheme developed for computing QCD jet cross sections in
perturbation theory. The double real and real-virtual contributions to
the second order radiative corrections, regularized by subtractions,
are finite in four space-time dimensions and their contribution to the
decay rate can be computed with any jet function defined in four dimensions.
We also demonstrate the finiteness of the regularized double virtual
correction analytically. We present the differential decay rate into
b-jets as a function of the jet resolution parameter for the JADE and
Durham clustering algorithms.
