 frontier of fundamental physics
Light weakly coupled states are predicted in many extensions of the Standard Model. I will review some efforts in detecting new light weakly coupled states, such as axions, dark photons and light dark matter. I will describe some of my recent work that relates to the cosmological manifestations of light particles, including a possible connection to the physics of the 21 cm line.
