Dark matter

The unequivocal evidence that the dominant form of matter in the Universe is fundamentally different from any visible matter is arguably the most striking example for the limitations of our current understanding of particle physics. At the same time, it provides one of the most compelling arguments for expecting ground-breaking discoveries in the near future. The search for this so-called dark matter is pursued by a wide range of different experiments, such as the Large Hadron Collider (LHC) and a whole new generation of low-background detectors aiming for the direct observation of DM interactions. Consequently, the next years offer an unprecedented opportunity for discovering the nature of DM.

A central challenge for this process will be to interpret the plethora of results, which requires new analysis tools for combining different experiments and inferring the resulting implications on DM models. The Junior Research Group of Prof. Felix Kahlhoefer addresses these issues by improving the theoretical framework and statistical methods used to interpret DM searches and by developing novel analysis and fitting tools. The aim of this work is to understand how existing and planned DM searches can be extended to probe previously unexplored parameter regions and thus enhance the chances for a discovery of DM.

The DM puzzle is one of the central problems of modern cosmology, astrophysics and particle physics and it will require information from a wide range of different experiments and observations to solve it. With ever-increasing sensitivity, the DM search programme is entering the age of data and putative signals rather than exclusion limits can be expected for the near future. When entering this new era, innovative approaches will become essential to fully exploit the complementarity of different DM experiments and maximize the information that can be extracted from data. Only a combination of all available experimental and theoretical results will make it possible to draw robust conclusions on the fundamental building blocks of the Universe.
