    Description: Title: Nuclear Dark Matter

    Abstract:
    I will outline models of Nuclear Dark Matter, where the dark matter states are large composite objects consisting of constituent "dark nucleons". I will present some of the details of the possible interactions of these large composite dark matter states with the Standard Model sector. Elastic scattering with SM nuclei can be coherently enhanced by factors as large as A^2, where A is the number of constituents in the composite state (there exist models in which DM states of very large A may be realised). This enhancement, for a given direct detection event rate, weakens the expected corresponding signals at colliders by up to 1/A. Moreover, the spatially extended nature of the DM states leads to an additional, characteristic form factor modifying the momentum dependence of scattering processes, altering the recoil energy spectra in direct detection experiments.

    Description: Title: Phenomenology of self-interacting WIMPs

    Abstract: The observed dark matter relic abundance and the idea of thermal freeze-out motivate dark matter particles with weak-scale interactions (so-called WIMPs). On the other hand, discrepancies between numerical simulations and observations on galactic scales prefer models in which dark matter particles have rather strong self-interactions. In my talk I will discuss how to combine these two classes of dark matter models by considering dark matter particles interacting via a new light mediator. I will introduce different types of mediators and discuss the relevant observational and experimental constraints. While the simplest realizations of this set-up are strongly constrained, a number of possible modifications open up a range of interesting possibilities.
