Combined Analysis of Neutrino and Antineutrino Oscillations at T2K
Abstract: and comprise 7.482 × 10 20 protons on target in neutrino mode, which yielded in the far detector 32 e-like and 135 μ-like events, and 7.471 × 10 20 protons on target in antineutrino mode, which yielded 4 e-like and 66 μ-like events. Reactor measurements of sin 2 2θ 13 have been used as an additional constraint. The one-dimensional confidence interval at 90% for the phase δ CP spans the range (−3.13, −0.39) for normal mass ordering. The CP conservation hypothesis (δ CP ¼ 0, π) is excluded at 90% C.L.

“…Under the normal (inverted) hierarchy assumption, |∆m 2 ee | yields ∆m 32 = (2.37 ± 0.11) × 10 −3 eV 2 (∆m 32 = −(2.47 ± 0.11) × 10 −3 eV 2 ). This result is consistent with and of compatible precision to measurements obtained from accelerator ν µ and ν µ disappearance [11,12]. The reconstructed positron energy spectrum observed in the far site is compared in Fig.…”
