17.07.2014 XENON100 sets tight limits on axions

One of the best motivated candidates for dark matter is the weakly interacting massive particle (WIMP) which is expected to be about 10-1000x heavier than a proton. However, there are also other candidates, one of them being the ultra-light axion or similar-behaving axion-like-particles (ALPs). In some sense, these are expected to behave like a photon with a tiny mass. XENON100, a ultra-sensitive dark matter experiment developed to search for WIMPs, has recently placed very tight constrains on ultra-light dark matter, in the form of axions and ALPs (publication).

The Laboratory for High Energy Physics (LHEP) is a division of the Physics Institute at the University of Bern, Switzerland.
We conduct research in the field of experimental particle physics. The six main subjects are:

The LHEP has also been involved in experiments on low energy QCD studies, strange-matter, quark-gluon plasma, etc.
