Addressing fundamental questions with astroparticle physics at low energy
Christian Weinheimer (Universität Münster)

Fundamental questions in astrophysics and cosmology such as the matter to antimatter asymmetry (baryon asymmetry) in the
universe or the existence of dark matter are thought to be closely linked to particle physics. For example, the baryon
asymmetry of the universe can be explained by models of leptogenesis, which require special properties of neutrinos. And
the as yet unknown dark matter presumably consists of particles that require physics beyond the standard model of
particle physics.
This question can be investigated using search and precision experiments in (astro)particle physics at low energies.
In this colloquium, this will be illustrated by three examples: the search for neutrinoless double beta decay, the direct
search for the neutrino mass and the direct search for dark matter. These searches will be explained using specific
experiments, such as the KATRIN and XENONnT experiments including their recent results,
as well as the respective perspectives for the future possibilities
