Hadronic Higgs boson decay at order $\alpha_s^4$ and $\alpha_s^5$
Abstract
We compute corrections to the decay of the Standard Model Higgs boson to hadrons, to the fourth order in the strong coupling constant . We use an effective theory in which the Higgs boson couples directly to bottom quarks and to gluons, via top quark--mediated effective couplings. Numerically, our results are of a comparable size to the previously-known "massless" contributions and complete the order corrections to the hadronic decay of the Higgs boson. In these proceedings we also provide an independent cross check of the gluonic Higgs boson decay at order .
