Electron Neutrinos From Muon Neutrinos!

New results from the T2K collaboration have been presented at a KEK Physics Seminar today, and they are really interesting stuff. In a nutshell, six electron neutrino events have been seen by their far detector, illuminated by a pure and intense beam of muon neutrinos. The estimated backgrounds from non-oscillating-neutrino sources are estimated to amount to 1.5+-0.3 events, and the observed counts thus constitute a 2.5-standard-deviation effect, hopefully a first hint of direct detection of nu_mu -> nu_e oscillations.read more
