Submission + - Muon neutrino to electron neutrino oscillation conclusively shown

Chris Greenley writes: The T2K long baseline neutrino experiment in Japan has just announced conclusive evidence for electron to muon neutrino oscillation at the 7.5 sigma level. (The level needed for discovery is 5 sigma.) This experiment generates a focused beam of electron neutrinos using an accelerating in the J-PARC facility north of Tokyo which is aimed at the massive Super-Kamiokande detector 295 KM (185 miles) away near the west coast of Japan.

This T2K observation is the first of its kind in that an explicit appearance of a unique flavor of neutrino at a detection point is unequivocally observed from a different flavor of neutrino at its production point.

This result clears the way for CP-violation neutrino studies which could show that "regular" neutrinos act differently than their antimatter counterparts, a phenomenon that so far has only been observed in quarks. If neutrino CP-violation is found, it could explain why there is such a large predominance of matter over antimatter in the universe.
