Short-baseline reactor antineutrino anomaly. The experimental results are compared to the prediction without oscillation, taking into account the new antineutrino spectra, the corrections of the neutron mean lifetime, and the off-equilibrium effects. Published experimental errors and antineutrino spectra errors are added in quadrature. The mean-averaged ratio including possible correlations is . As an illustration, the red line shows a 3 active neutrino mixing solution fitting the data, with . The blue line displays a solution including a new neutrino mass state, such as and = 0.12, as well as .
