20.11.2014 OPERA achieves its science goal

The OPERA experiment aimed at the first observation of oscillations from muon neutrinos into tau neutrinos in appearance mode. It recently reported the "observation" of the appearance of tau neutrinos in a pure muon neutrino beam from CERN, after travelling over 730 km through the Earth's crust. We have analyzed about 20'000 neutrino events recorded in 5 years of data taking and confirmed the observation of 4 tau neutrino events, leading to a 4.2 σ statistical significance.

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.
