Reactor antineutrino anomaly

Recently new reactor antineutrino spectra have been provided for 235U, 239Pu, 241Pu and 238U, increasing the mean flux by about 3 percent. To good approximation, this reevaluation applies to all reactor neutrino experiments. The synthesis of published experiments at reactor-detector distances 1.5 eV^2 (99%) and sin^2(2\theta_{new})=0.17(0.1) (95%). Constraints on the theta13 neutrino mixing angle are revised.
