A less simplified model: 2HDM+pseudoscalar

This presentation covers the topic of dark matter searches in the context of models with an extended Higgs sector, such as Two-Higgs-Doublet Models (2HDMs). This includes mono- Higgs signatures specific to simplified models, like the 2HDM with a vector/axialvector mediator (2HDM+Z'), and simplified dark matter models with a scalar or pseudoscalar mediator. Specific emphasis should be placed on the new, less simplified benchmark model recently adopted by ATLAS and CMS: the 2HDM+pseudoscalar benchmark with its rich phenomenology of collider signatures.
