First look at antineutrino appearance from T2K

The T2K (Tokai-to-Kamioka) experiment in Japan has observed three electron antineutrino candidate events in a muon antineutrino beam. T2K creates and monitors a muon antineutrino beam at the J-PARC facility in Tokai village on the east coast of Japan, and sends it 295 km west to the Super-Kamiokande detector underneath Mt. Ikeno near Toyama, which was built, and is operated, by ICRR. This is the first antineutrino appearance search by
