Description
The T2K Collaboration reports evidence for electron neutrino appearance at the atmospheric mass splitting, . An excess of electron neutrino interactions over background <?format ?>is observed from a muon neutrino beam with a peak energy of 0.6 GeV at the Super-Kamiokande (SK) detector 295 km from the beam’s origin. Signal and background predictions are constrained <?format ?>by data from near detectors located 280 m from the neutrino production target. We observe 11 electron neutrino candidate events at the SK detector when a background of events is expected. The background-only hypothesis is rejected with a value of 0.0009 (), and a fit assuming <?format ?> oscillations with sin⁡22θ23=1, and yields sin⁡22θ13=0.088-0.039+0.049(stat+syst).
