Production and Detection
of Very Light Bosons


Shining light through walls?

Many unified theories of elementary particles predict the existence of new particles which are so light and weakly interacting with the known particles that they have escaped detection so far.

Such particles can be searched for in a light shining through walls experiment. The idea (see figure) is to send a laser beam along a transverse magnetic field. A fraction of the laser photons will transform into the new particles. The latter will propagate freely through a wall, without being absorbed, Finally, another magnetic field located on the other side of the wall can transform back some of these new particles into photons -- apparently regenerating photons out of nothing.

The Axion-Like Particle Search (ALPS) collaboration is running a photon regeneration experiment at DESY which exploits powerful solid-state lasers. This experiment has taken first data in September 2007 and is continuously improved.
