20.05.2015 T2K confirms muon-antineutrino disappearance

The T2K experiment has recently released its first results on the disappearance of muon antineutrinos. It is based on the analysis of neutrino and antineutrino interactions generated by 2.3x1020 protons on target, delivered between May 2014 and March 2015 by a beam mainly composed of muon antineutrinos. Out of the 59.8 events which were predicted in case of no neutrino oscillations, only 17 muon-like events were observed in the Super-Kamiokande detector, which is 295 km away from the neutrino source. This confirms unambiguously the hypothesis of antineutrino disappearance.

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.
