Dark Plasma and Dark Atoms
Abstract: Atom-like structures in the dark matter sector are generally believed to be only possible if the dark sector is asymmetric, in analogy with baryon number in the visible sector. In this talk we discuss how, given the right particle content and couplings, it might be possible to generate dark atoms thermally, i.e. without an asymmetry. Besides being an interesting proof of concept, such models might be relevant to explain non-gravitational interactions of dark matter and can lead to new phenomena like dark plasma interactions.

A new high precision search for neutron-antineutron oscillations at the ESS
Abstract: In this talk I shall discuss how a search for neutron-antineutron oscillations can be carried out at the European Spallation Source. It will be shown how such oscillations can provide a unique probe of some of the central questions in particle physics and cosmology: the energy scale and mechanism for baryon number violation, the origin of the baryon-antibaryon asymmetry of the universe, and the mechanism for neutrino mass generation. An overview of the proposed experiment and its capability to a sensitivity to the oscillation probability, which is three orders of magnitude greater than previously obtained, will be given. The international collaboration which has been formed to carry out the proposed work will also be described.
