T2K experiment confirms electron neutrino appearance

July 19, 2013

The T2K experiment has reported new results establishing the transformation of muon neutrinos into electron neutrinos. The statistical significance has crossed the 5-sigma barrier, a benchmark widely regarded as a requirement for the definitive observation of a new phenomenon.
