The Neutron and the Universe
Stephan Paul (TU München)
Seminar room 3, 15:00
The history of the early universe offers several key puzzles: the the matter/antimatter asymmetry, the left-handedness of the Universe and the primordial nucleosynthesis. All these questions are directly related to discrete symmetries and their violation. Neutrons offer an approach complementary to accelerator experiments, to address these puzzles. Since about a decade, particle physics with neutrons is also used to address gravity and gravity-like forces with unprecedented precision. This maybe one of the very few ways, how to tackle issues relevant to the very early Universe. The talk will give an overview on the physics and the experimental approaches and will highlight some of the challenges.
