STEREO neutrino spectrum of ²³⁵U fission rejects sterile neutrino hypothesis

NUCLEAR REACTIONS ²³⁵U(n, F)ν-bar, E thermal; ¹H(ν-bar, e⁺), E ∼ 2 MeV; measured reaction products, En, In, Eβ, Iβ; deduced antineutrino flux, rejection of the sterile neutrino hypothesis, antineutrino energy spectrum anomalies originate from biases in the nuclear experimental data used for the predictions. The Institut Laue-Langevin (ILL) research reactor.
