8. Self-heating dark matter: semi-annihilation + self-interaction

Ayuki Kamada (CTPU IBS)

Thermal freeze-out of dark matter is a prominent mechanism to explain the relic abundance. There are several processes suggested to govern thermal freeze-out: pair-annihilation, semi-annihilation, and 3-to-2 process. Among them, semi-annihilation is distinctive. It causes an efficient conversion from the mass energy into the kinetic energy in collaboration with self-interaction. This...

9. Nu physics in direct detection experiments

Direct detection experiments are probing the nature of dark matter particles with increasing sensitivities by looking for their scattering off nuclei (or electrons) in underground detectors. Future experiments, with increased payloads and lower energy thresholds, will have access to wide areas of the parameter space. The search for dark matter is, however, limited by a Standard Model...

23. The dark matter component of the Gaia anisotropic substructure

Nassim Bozorgnia (IPPP, Durham University)

Recently, a prominent population of stars with a high radial velocity anisotropy has been discovered in the inner stellar halo, using the second data release from the Gaia satellite. An important question regarding this stellar structure is the properties of its unknown dark matter component in the Solar neighborhood. Determining the fraction and anisotropy of this dark matter component is...
