Constraints to Dark Matter from Inert Higgs Doublet Model

TL;DR

This paper investigates the Inert Higgs Doublet Model, identifying viable dark matter mass regions and proposing experimental strategies for detection through direct detection and collider searches.

Contribution

It identifies three mass regions where inert scalar Higgs can account for dark matter, ruling out the low mass region and highlighting the importance of future experiments.

Findings

Low mass region (3-50 GeV) is ruled out.

Intermediate (60-100 GeV) and high (>550 GeV) mass regions are testable by upcoming experiments.

Collider searches should focus on D± → HW± decay in jets plus missing energy channels.

Abstract

We study the Inert Higgs Doublet Model and its inert scalar Higgs $H$ as the only source for dark matter. It is found that three mass regions of the inert scalar Higgs can give the correct dark matter relic density. The low mass region (between 3 and 50 GeV) is ruled out. New direct dark matter detection experiments will probe the intermediate (between 60 and 100 GeV) and high (heavier than 550 GeV) mass regions. Collider experiments are advised to search for $D^\pm \to HW^\pm$ decay in the two jets plus missing energy channel.
