(2) Fundamental physics
[PIs: Dreiner, Kramer, Meißner, Nilles ]
The methods described in (1) "Strongly correlated matter" will also be used to unravel mysteries related to yet unmeasured properties of matter, such as the electric dipole moments of nucleons and light nuclei. More generally, the effects of physics beyond the Standard Model in the decays and reactions of hadrons will be studied, which is extensively searched for at colliders world-wide. This is complemented and strengthened on one side by research on supersymmetric model building with numerical investigations to explore the limits of the parameter space from the LHC data and on the other side by investigations of the landscape of string theory. More precisely, systematic studies of the heterotic mini-landscape using automated tools will be done as well as investigations of related phenomena of early universe cosmology, that naturally lead to the “multiverse”, an ensemble of universes with different properties. Here, we notice a strong connection to the CST, where corresponding questions concerning the anthropic reasoning so prominent in the landscape discussion will further be investigated. All this is supplemented by precision tests of general relativity and the determination of neutron star properties, which are yet another manifestation of strongly interacting complex matter.
