Abstract |
Most of the matter in our universe is in the form of dark matter. The research of the past decades led to
the development of two canonical paradigms for its properties: the collisionless cold dark matter
paradigm, supported by the observed gravitational clustering, and the WIMP paradigm, which provides a
well-motivated particle physics framework for collisionless cold dark matter. However, current
observational and experimental results motivate looking beyond these scenarios. I will discuss some of
this motivation, and new directions and challenges in exploring the phenomenology of dark matter with
different particle physics interactions than in the canonical scenario. |
