Indication of electron neutrino appearance from an accelerator-produced off-axis muon neutrino beam

Abstract:

The T2K experiment observes indications of νμ→ν e appearance in data accumulated with 1.43×1020 protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm232|=2.4×10⊃- 3eV2, ⊃sin⊃ 22θ23=1 and ⊃sin⊃ 22θ13=0, the expected number of such events is 1.5±0.3(syst). Under this hypothesis, the probability to observe six or more candidate events is 7×10⊃-3, equivalent to 2.5σ significance. At 90% C.L., the data are consistent...
