Heavy Higgs Boson Production at Colliders in the Singlet-Triplet Scotogenic Dark Matter Model

TL;DR

This paper explores the production and detection of heavy Higgs bosons within a singlet-triplet scotogenic dark matter model, linking neutrino mass generation with dark matter stability and collider phenomenology.

Contribution

It introduces a consistent parameter space for the model that aligns with neutrino and dark matter observations, and analyzes heavy Higgs signatures at colliders.

Findings

Parameter sets compatible with neutrino mass and dark matter abundance

Predicted heavy Higgs signatures at LHC and future colliders

Characterization of collider phenomenology for the model

Abstract

We consider the possibility that the dark matter particle is a scalar WIMP messenger associated to neutrino mass generation, made stable by the same symmetry responsible for the radiative origin of neutrino mass. We focus on some of the implications of this proposal as realized within the singlet-triplet scotogenic dark matter model.We identify consistent parameter sets consistent both with neutrino mass and the observed dark matter abundance. Finally we characterize the expected phenomenological profile of heavy Higgs boson physics at the LHC as well as at future linear Colliders.
