Fundamental physics with slow neutrons — •Oliver Zimmer — Physik-Department E18, TU München

Slow neutrons are an excellent tool to study fundamental symmetries and interactions. Experiments aim at highest precision at lowest energies and thus provide information complementary to high-energy physics and with strong links to astrophysics and cosmology. A plethora of investigations comprises studies of neutron-nucleus interactions, static neutron properties and neutron decay properties. For sensitive tests of the standard model of particle physics as well as for their cosmological implications in the creation of baryonic matter and of the light chemical elements, the electric dipole moment and the lifetime of the neutron stand in the focus of present interest. They are both investigated using trapped ultracold neutrons (UCN). As an important prerequisite the improvement of UCN sources ranks on top of the agenda of many research groups around the world. This talk shall give an overview of the field of particle physics with slow neutrons with emphasis on most recent developments.
