Higgs-portal Scalar Dark Matter: Scattering Cross Section and Observable Limits

TL;DR

This paper investigates a simple Higgs-portal scalar dark matter model, analyzing direct detection limits, self-interacting effects on structure formation, and comparing experimental constraints from LHC and Xenon 1T.

Contribution

It provides a comprehensive analysis of the Higgs-portal scalar dark matter model, including self-interaction effects and experimental constraints, which was less explored in prior work.

Findings

Direct detection limits on resonant and large mass regions established.

Self-interacting effects influence large scale structure formation.

Comparison of collider and direct detection constraints performed.

Abstract

The simplest Higgs-portal dark matter model is studied in the light of dark matter self-interacting effects on the formation of large scale structures. We show the direct detection limits on the resonant and large mass regions. Finally, we also compare these limits with those at the LHC and Xenon 1T experiments.
