Revisiting one-loop corrections to the trilinear Higgs boson self-coupling in the Inert Doublet Model

Abstract

We investigate predictions of the trilinear Higgs self-coupling with radiative corrections in the context of the Inert Doublet Model. The triple Higgs vertex is computed at the one-loop level based on the on-shell renormalization scheme. We calculate its possible deviation from the predictions within the standard model, taking into account all relevant theoretical and experimental constraints, including dark matter searches and the latest bounds on the branching fraction of the Higgs boson decaying to invisible particles. By scanning the model's parameter space, we find that the deviation in the triple Higgs boson self-coupling from standard model expectations can be substantial, exceeding 100\% in certain regions of the parameter space.
