Four-Neutrino Analysis of 1.5 km Baseline Reactor Antineutrino Oscillations

Figure 3

The data and error bars are the reproduction of updated RENO for an extended period until October 2012. The red fits are drawn with sin²2𝜃₁₄=0 for Δ𝑚²₃₁=2.83×10⁻³eV² and for Δ𝑚²₃₁=2.32×10⁻³eV² obtained from the analysis in Figure 4. For each case, the blue fits are overlaid which are the superposition with Δ𝑚²₄₁=0.039eV² oscillation of amplitude sin²2𝜃₁₄=0.050, and the superposition with Δ𝑚²₄₁=0.0078eV² oscillation of amplitude sin²2𝜃₁₄=0.054, respectively, obtained from the analysis in Figure 5.
