ABSTRACT

We report Neutrino-4 experiment results of measurements of reactor antineutrinos flux and spectrum dependence on the distance in range 6–12 m from the center of the reactor core. The fit of experimental dependence with the law 1/L2, where L is the distance from the reactor center, gave satisfactory result with goodness of fit 81%. However, we discovered that the experimental neutrino spectrum is different from the calculated one. Using experimental spectrum, we performed the model independent analysis of restrictions on oscillation parameters Δm142 and sin2 2θ14. The results of this analysis exclude area of reactor and gallium anomaly at CL more than 99.7% (>3σ) for values Δm142 < 3 eV2 and sin2 2θ14 > 0.1. However, we observed an oscillation effect at CL 2.8σ in vicinity of Δm142 Δm142 ≈ 7.3 eV2 and sin2 2θ14 ≈ 0.39. The method of coherent addition of results of measurements, which allows us to directly observe the effect of oscillations, is proposed. The analysis of that effect is presented. In general, it seems that the effect predicted in gallium and reactor experiments is being confirmed but at sufficiently large value of Δm142. Future prospects of the experiment are discussed.

    "description": "We report Neutrino-4 experiment results of measurements of reactor antineutrinos flux and spectrum dependence on the distance in range 6\u201312 m from the center of the reactor core. The fit of experimental dependence with the law 1/L2, where L is the distance from the reactor center, gave satisfactory result with goodness of fit 81%. However, we discovered that the experimental neutrino spectrum is different from the calculated one. Using experimental spectrum, we performed the model independent analysis of restrictions on oscillation parameters \u0394m142 and sin2 2\u03b814. The results of this analysis exclude area of reactor and gallium anomaly at CL more than 99.7% (>3\u03c3) for values \u0394m142 < 3 eV2 and sin2 2\u03b814 > 0.1. However, we observed an oscillation effect at CL 2.8\u03c3 in vicinity of \u0394m142 \u0394m142 \u2248 7.3 eV2 and sin2 2\u03b814 \u2248 0.39. The method of coherent addition of results of measurements, which allows us to directly observe the effect of oscillations, is proposed. The analysis of that effect is presented. In general, it seems that the effect predicted in gallium and reactor experiments is being confirmed but at sufficiently large value of \u0394m142. Future prospects of the experiment are discussed.",
