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.
