T2K presents first CP violation search result

2016/8/7

The international T2K Collaboration announced today their findings on the symmetry between neutrino and antineutrino oscillation. With nearly twice the antineutrino data in 2016 compared to their initial results using antineutrino data in 2015, T2K has performed a new analysis of all data, fitting both neutrino and antineutrino modes simultaneously. Today's announcement was made by Konosuke Iwamoto, of the University of Rochester, who presented the results at the 38th International Conference on High Energy Physics in Chicago. (LINK) T2K's new data continue the trends observed in 2015, which is a preference for maximal disappearance of muon neutrinos, as well as a discrepancy between the electron neutrino and electron antineutrino appearance rates.
