Description
We have computed the electroweak corrections to H → Z Z* → 4 charged leptons, including the effect of anomalous HHH coupling in the κ-framework. The results of this scaling are gauge invariant. We have computed the results for H → e +e −µ +µ − and H → e +e −e +e − processes. The corrections for both processes depend on the input parameter scheme. In the GF scheme, the electroweak corrections are about 1.26% for the H → e +e −µ +µ − and about 0.25% for the H → e +e −e +e − process. However, changing the κ from 4 to −4, the corrections vary from less than 1% to about −6%. We have plotted a number of kinematic distributions. The corrections over most of the phase space regions are similar. These large corrections can be used to put a bound on the HHH coupling. This can help in determining the structure of the Higgs potential.
