# IDM and not only

## TL;DR

This paper reviews recent updates to the Inert Doublet Model (IDM), showing how new direct detection constraints limit its parameter space and exploring an extended version with a complex singlet.

## Contribution

It provides updated constraints on IDM and introduces the IDMS extension with a complex singlet, expanding the model's scope.

## Key findings

- Updated direct detection constraints significantly reduce IDM parameter space
- Inclusion of IDMS extension broadens the model's phenomenology
- The allowed parameter space for IDM is more restricted than previously thought

## Abstract

In this note, we discuss recent updates to a previous scan for the Inert Doublet Model, a two Higgs doublet model with a dark matter candidate. We explicitly show the inclusion of updated constraints on direct detection reduces the allowed parameter space significantly. We furthermore discuss the IDMS - an extension of the IDM with a complex singlet.
