N3LO predictions for the decay of the Higgs boson to bottom quarks
Abstract We present a fully-differential calculation of the H → b b ¯ $$ H\to b\overline{b} $$ decay at next-to-next-to-next-to-leading order (N3LO) accuracy. Our calculation considers diagrams in which the Higgs boson couples directly to the bottom quarks, i.e. the perturbative order we consider is...

| Summary: | Abstract We present a fully-differential calculation of the H → b b ¯ $$ H\to b\overline{b} $$ decay at next-to-next-to-next-to-leading order (N3LO) accuracy. Our calculation considers diagrams in which the Higgs boson couples directly to the bottom quarks, i.e. the perturbative order we consider is O α s 3 y b 2 $$ \mathcal{O}\left({\alpha}_s^3{y}_b^2\right) $$ . In order to regulate the infrared divergences present at this order we use the Projection-to-Born technique coupled with N -jettiness slicing. After validating our methodology at next-to-next-to-leading order (NNLO) we present exclusive jet rates and differential distributions for jet observables at N3LO accuracy using the Durham jet algorithm in the Higgs rest frame. |
