“…To accommodate massive b quarks, we employed a recent computation [27] of the NNLO QCD corrections to H → bb that fully accounts for the b-quark mass. That computation is based on the nested soft-collinear subtraction scheme adapted to deal with massive particles.…”

“…[21] to include b-quark mass effects in the theoretical description of Higgs production in association with a vector boson. To this end, we combined the recent NNLO QCD description of the Higgs boson decay into two massive b quarks [27] 1 with the computation of NNLO QCD corrections to the production process [21,29] which required small modifications because of the b-quark mass.…”

We present a computation of next-to-next-to-leading-order (NNLO) QCD corrections to the production of a Higgs boson in association with a W boson at the LHC followed by the decay of the Higgs boson to a bb pair. At variance with previous NNLO QCD studies of the same process, we treat b quarks as massive. An important advantage of working with massive b quarks is that it makes the use of flavor jet algorithms unnecessary and allows us to employ conventional jet algorithms to define b jets. We compare NNLO QCD descriptions of the associated WHðbbÞ production with massive and massless b quarks and also contrast them with the results provided by parton showers. We find Oð5%Þ differences in fiducial cross sections computed with massless and massive b quarks. We also observe that much larger differences between massless and massive results, as well as between fixed-order and parton-shower results, can arise in selected kinematic distributions.

We consider the double-soft limit of QCD amplitudes with two massive quarks in a back-to-back kinematics accompanied by two soft partons. We integrate analytically the respective double-soft eikonal functions over the phase space of the two soft partons. Within the context of the nested soft-collinear subtraction scheme, our results may serve as one of the integrated subtraction terms needed for the analytic and fully-differential description of next-to-next-to-leading order (NNLO) QCD corrections to colour-singlet decay into massive partons or to heavy-quark pair production.
