Query: The Reactor Anomaly after Daya Bay and RENO   Gallium and short baseline reactor neutrino experiments indicate a
short-distance anomalous disappearance of electron antineutrinos which, if
interpreted in terms of neutrino oscillations, would lead to a sterile neutrino
mass inconsistent with standard cosmological models. This anomaly is difficult
to measure at 1 km baseline experiments because its disappearance effects are
degenerate with that of theta_13. The flux normalization independent
measurement of theta_13 at Daya Bay breaks this degeneracy, allowing an
unambiguous differentiation of 1-3 neutrino oscillations and the anomalous
disappearance at Double Chooz and RENO. The resulting anomaly is consistent
with that found at very short baselines and suggests a downward revision of
RENO's result for theta_13. A MCMC global analysis of current cosmological data
shows that a quintom cosmology is just compatible at 2 sigma with a sterile
neutrino with the right mass to reproduce the reactor anomaly and to a lesser
extent the gallium and LSND/MiniBooNE anomalies. However models in which the
sterile neutrino acquires a chameleon mass easily satisfy the cosmological
bounds and also reduce the tension between LSND and KARMEN.
