Dark matter self-interactions have important implications for the distributions of dark matter in the Universe, from dwarf galaxies to galaxy clusters. In this talk, we present benchmark models that illustrate characteristic features of dark matter that is self-interacting through a new light mediator. These models have self-interactions large enough to change dark matter densities in the...

Dark matter direct detection analyses have typically relied on two types of contact operators that mediate the interaction between dark matter and the target nuclei. Other contact operators, such as {\it pseudoscalar}-type operators, are almost universally neglected in the literature; the reason being that in the non-relativistic approximation, these operators are suppressed by powers of...

54. Dark Matter Detectors as Dark Photon Helioscopes

oral

Light new particles with masses below 10 keV, often considered as a plausible extension of the Standard Model, will be emitted from the solar interior, and can be detected on the Earth with a variety of experimental tools. Here we analyze the new "dark" vector state V, a massive vector boson mixed with the photon via an angle kappa, that in the limit of the small mass m_V has its emission...
