A bstractThe Double Chooz experiment presents improved measurements of the neutrino mixing angle θ13 using the data collected in 467.90 live days from a detector positioned at an average distance of 1050 m from two reactor cores at the Chooz nuclear power plant. Several novel techniques have been developed to achieve significant reductions of the backgrounds and systematic uncertainties with respect to previous publications, whereas the efficiency of the ν¯e$$ {\overline{\nu}}_e $$ signal has…

First Search for Short-Baseline Neutrino Oscillations at HFIR with PROSPECT.
A reactor model independent analysis of the inverse beta decay prompt energy spectrum as a function of baseline constrains significant portions of the previously allowed sterile neutrino oscillation parameter space at 95% confidence level and disfavors the best fit of the reactor antineutrino anomaly.

Experimental determination of the antineutrino spectrum of the fission products of U238.
An experiment was performed at the scientific neutron source FRM II in Garching to determine the cumulative antineutrino spectrum of the fission products of U238, which reveals a spectral distortion of ∼10% but returns the same value for the mean cross section per fission for the inverse beta decay.
