Higgs-Boson Decays: Updates
Abstract
In this contribution, new developments for the Standard Model Higgs-boson decays will be summarized. This addresses extensions of the grids used by Hdecay to implement finite NLO mass effects for H gg as well as explicit numbers for the branching fraction for the strange-Yukawa induced part of H s s together with the related uncertainties. In addition, first results of the strong and weak Dalitz decays of the Higgs-boson decays H s s + g/γ are presented. The Dalitz decays define the separation between the Yukawa-induced part and the continuum, that is not induced by the strange-Yukawa coupling, and thus pave the way towards a solid determination of the strange-Yukawa coupling at future e+e- colliders, but will also be relevant for solid bounds on the strange-Yukawa coupling at the LHC.
