Contribution

It analyzes the discovery prospects of the Inert Doublet Model and THDMa at future lepton colliders, highlighting their distinctive signatures and detection strategies.

Findings

Electroweak gauge bosons plus missing energy signatures are promising for dark matter detection.

Future lepton colliders can significantly improve sensitivity to Inert Doublet Model and THDMa.

Results are based on comprehensive analysis from Snowmass Whitepaper arXiv:2203.07913.

Abstract

I will briefly discuss the signatures and discovery prospects of several new physics models containing dark matter candidates at future lepton colliders. In particular, I will discuss the two models that, among other signatures, lead to electroweak gauge bosons and missing energy: the Inert Doublet Model, as well as the THDMa, a two Higgs doublet model with an additional pseudoscalar that serves as a portal to the dark sector. Results are mainly based on a Snowmass Whitepaper arXiv:2203.07913
