Higgs decay into massive b-quarks at NNLO QCD in the nested soft-collinear subtraction scheme
read the original abstract
We present a fully differential description of a decay of a scalar Higgs boson into massive b-quarks valid at next-to-next-to-leading order (NNLO) in perturbative quantum chromodynamics (QCD). We work within the nested soft-collinear subtraction scheme extended to accommodate massive partons. We include the loop-induced contribution involving a Higgs coupling to a top quark. We test our calculation against results existing in the literature, comparing the predictions for the total decay width and jet rates.

Higgs boson decay to massive bottom quarks at order $\alpha_s^4$ induced by top-quark Yukawa couplings
The O(α_s^4) top-Yukawa-induced correction to H→bb is computed analytically, increasing the width by 0.4% and lowering scale uncertainty to 0.4%.
