Note on Unitarity Constraints in a Model for a Singlet Scalar Dark Matter Candidate
arXiv:hep-ph/0410102
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.
