Abstract:
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 which have only very weak
interactions with the visible sector Standard Model particles. Some of
these exotic particle candidates (such as e.g. "axions", "axion-like
particles (ALPs)" and "hidden or dark photons") may be very light.
Correspondingly, these very weakly interacting slim particles (WISPs)
may lead to observable effects in experiments exploiting intense photon
and electron beams: light-shining-through a wall and beam dump
experiments, respectively. We present the physics case and a status
report of this emerging low-energy, but high intensity frontier of
particle physics.
