Abstract
Despite the discovery of the Higgs boson, the Higgs sector of the standard model is still not fully established. In particular, the self-couplings of the Higgs boson, and its couplings with gauge bosons, are still to be fully determined. We consider electroweak corrections to the process [Formula: see text]. The corrections depend on the [Formula: see text] and [Formula: see text] couplings. We investigate this dependence in [Formula: see text]-framework. We find that the width depends on [Formula: see text] coupling significantly. The dependence on [Formula: see text] coupling is only marginal. We also discuss the dependence on [Formula: see text] coupling.
