Overview of particle dark matter models.
Axions generically emerge in many contexts of particle physics. They may also solve long standing theoretical problems such as the strong CP, gauge hierarchy and the cosmological constant problems. In this talk, I will briefly discuss these theoretical ideas and focus on new experimental methods to find these particles
Electroweak singlets, sterile neutrinos, remain viable dark matter candidates. It is tantalizing that much remains mysterious about the physics of the neutrino sector. Luckily, neutrinos impact key issues in cosmology and compact objects, and new physics in this sector therefore may reveal itself. Moreover, the advent of new neutrino experiments, and planned next generation X-ray...
The generalization of dark matter to dark sectors, with potentially rich matter content and interactions, has opened up new avenues for detection. In particular, there are now many new motivations for light, long-lived particles, which can be probed by novel experiments at accelerators. I will review these motivations, describe of the interplay of theory and experiment in this area, and give...
