CosmoBit: Towards global fits of particle physics and cosmology for dark matter — •Patrick Stoecker — Institute for Theoretical Particle Physics and Cosmology, RWTH Aachen, Germany

The absence of a conclusive dark matter signal casts doubts on the conventional WIMP scenario. Alternative production mechanisms as well as models with an extended self interacting dark sector may explain the absence of a signal in these searches while opening up a new window of strong signals in cosmological observables like the primordial element abundances, the spectrum of the Cosmic Microwave Background as well as large scale structures.

In order to explore the parameter space of such models, it is therefore necessary to combine cosmological information with the constraints from traditional searches for particle dark matter. I will present the recent efforts to perform such a combination in the context of global fits within CosmoBit, a future part within the framework of GAMBIT (Global and Modular Beyond-the-Standard-Model Inference Tool).
