Description

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 processes H --> ve ve~ vm vm~ and H --> e+ e- mu+ mu-. The corrections depend on the HHH coupling. We investigate this dependence in the kappa-framework without violating gauge invariance. We find that the width depends on coupling significantly.
