Description
Most embeddings of the standard model into a more unified theory, in particular the ones based on supergravity or superstrings, predict the existence of a hidden sector of particles and interactions which have only very weak interactions with the visible sector standard model particles. Some of these exotic particle candidates (such as e.g. "axion-like particles" and "hidden U(1) gauge bosons") may be very light, with masses in the sub-eV scale, and have very weak interactions with photons. Correspondingly, they may be searched for in experiments exploiting high fluxes of low energy photons and/or large electromagnetic fields. We will present the physics case and a status report of this emerging low energy frontier of fundamental physics.
