TL;DR

This paper analyzes one-loop on-shell and off-shell Higgs decays into vector bosons and their impact on Higgs production at future electron-electron colliders, emphasizing the importance of including these effects for accurate predictions.

Contribution

It provides a detailed calculation of one-loop on-shell and off-shell Higgs decays into vector bosons and assesses their significance in Higgs production at $e^-e^-$ colliders.

Findings

One-loop Higgs decays significantly affect Higgs production.

Off-shell effects are important at future $e^-e^-$ colliders.

Neglecting these effects could lead to inaccurate predictions.

Abstract

One-loop on-shell and off-shell decays $H\rightarrow VV$ with $VV=\gamma\gamma, Z\gamma, ZZ$ are presented in this paper. The effects of one-loop on-shell and off-shell Higgs decays in Higgs productions at $e^-e^-$ collisions are also then examined. We find that the impacts of one-loop Higgs decays are significant and they are must be taken into account at $e^-e^-$ collision.
