Dark matter from WIMP to FIMP over three regimes: Cosmology versus Colliders

TL;DR

This paper explores different regimes of dark matter models, focusing on how their cosmological history and interactions influence signals in cosmology and collider experiments, emphasizing the interplay between these fields.

Contribution

It categorizes dark matter interactions into three regimes and highlights the connection between cosmological evolution and collider signatures.

Findings

Different regimes affect dark matter detection prospects.

Cosmology and collider signals are interconnected.

Feebly coupled dark matter models have distinct signatures.

Abstract

Dark matter models can give rise to specific signatures at particle physics experiments or in cosmology. The details of the cosmological history can also influence the new physics signals to be expected at e.g. collider experiments. In these proceedings, we briefly summarize the case of dark matter weakly to feebly coupled to Standard Model fermions through t-channel portal dividing the discussion into three main regimes. We also underline the interplay between cosmology and particle physics.
