Note on Unitarity Constraints in a Model for a Singlet Scalar Dark Matter Candidate

TL;DR

This paper examines how perturbative unitarity limits the self-couplings in a scalar dark matter model involving a singlet scalar, ensuring theoretical consistency of the model.

Contribution

It provides a detailed analysis of unitarity constraints specifically for a singlet scalar dark matter model, which was not extensively studied before.

Findings

Perturbative unitarity constrains scalar self-couplings.

Elastic scattering processes impose bounds on model parameters.

Results help ensure the model's theoretical viability.

Abstract

We investigate perturbative unitarity constraints in a model for a singlet scalar dark matter candidate. Considering elastic two particle scattering processes of the Higgs particle and the dark matter candidate, a real Klein-Gordon scalar field, perturbative unitarity constrains the self-couplings of the scalar fields.
