Phenomenological Implications of the Dark Phases of the N2HDM — •Isabell Engeln¹, Margarete Mühlleitner¹, Rui Santos^2,3,4, and Jonas Wittbrodt⁵ — ¹ITP, Karlsruher Institut für Technologie (KIT), Karlsruhe, Germany — ²ISEL, Instituto Politécnico de Lisboa, Lisboa, Portugal — ³CFTC, Universidade de Lisboa, Lisboa, Portugal — ⁴LIP, Departamento de Física, Universidade do Minho, Braga, Portugal — ⁵Deutsches Elektronen-Synchrotron (DESY), Hamburg, Germany

The N2HDM is based on the CP-conserving 2HDM extended by a real scalar singlet field. This model allows for three different dark phases with either one of the two doublets or the singlet being inert, or both. This gives rise to dark matter candidates that originate from different sectors. In this talk, we compare the phenomenology of the inert doublet and the inert singlet phase based on parameter scans of both phases, considering all applicable theoretical and experimental constraints. We discuss differences and similarities and point out possible ways to distinguish between the phases at current or future collider experiments.
