Four-Neutrino Analysis of 1.5 km Baseline Reactor Antineutrino Oscillations

Figure 1

The dependency of ⟨𝑃⟩ in (5) on Δ𝑚²₄₁ is presented, when Δ𝑚²₃₁=2.32×10⁻³eV² as taken in RENO and Daya Bay. Typical shapes of ⟨𝑃⟩ versus distance are drawn for comparison with the measured ratios in the two experiments. The amplitudes of Δ𝑚²₃₁ oscillation and Δ𝑚²₄₁ oscillation are given by sin²2𝜃₁₃=0.10 and sin²2𝜃₁₄=0.10, respectively, as an example.
