Description
Dark sectors, which introduce new particles neutral under the Standard Model, arise in many models of New Physics. These particles would only interact feebly with ordinary matter, and could easily have escaped detection in past experimental searches. This possibility has recently received much attention in the context of dark matter models, introducing dark sector particles charged under a new Abelian gauge group. The corresponding gauge boson, the dark photon, couples the dark sector to Standard Model particles. Its mass must lie in the MeV - GeV range to explain recent anomalies, making it accessible to low-energy experiments. In this talk, I'll review the motivation and phenomenology of dark sectors, and discuss recent and future experiments designed to search for these particles.
