16.06.2015 A fifth tau-neutrino detected at Gran Sasso

The OPERA neutrino experiment located at the Gran Sasso Underground Laboratory (LNGS) in Italy has announced the detection of its 5th tau-neutrino candidate. This allows the collaboration claiming the discovery of the muon- to tau-neutrino oscillation channel, with a statistical sensitivity exceeding 5 standard deviations. This channel is particularly relevant since is the one occurring for atmospheric neutrino and it had not yet been seen in direct appearance, as done now (unambiguously) by OPERA.

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.
