چکیده

We revisit the reactor antineutrino anomaly using the recent reactor flux independent determination of sizable 13 by considering the full set of the absolute reactor e flux measurements. When normalized to the predicted flux of Mueller et al. [Phys. Rev. C 83, 054615 (2011)], the new world average, after including results from Palo Verde, Chooz, and Double Chooz, is 0:959 0:009 (experiment uncertainty) 0:027 (flux systematics). Including the data with kilometer baseline, the new world average is only about 1:4 lower than the unity, weakening the significance of the reactor antineutrino anomaly. The upcoming results from Daya Bay, RENO, and the Double Chooz will provide further information about this issue.

Contribution of recently measured nuclear data to reactor antineutrino energy spectra predictions

This paper attempts to summarize the actual problematic of reactor antineutrino energy spectra in the frame of fundamental and applied neutrino physics. Nuclear physics is an important ingredient of reactor antineutrino experiments. These experiments are motivated by neutrino oscillations, i.e. the measure of the 13 mixing angle. In 2011, after a new computation of the reactor antineutrino ener...

We present a review of the antineutrino spectra emitted from reactors. Knowledge of these and their associated uncertainties are crucial for neutrino oscillation studies. The spectra used to-date have been determined by either conversion of measured electron spectra to antineutrino spectra or by summing over all of the thousands of transitions that makeup the spectra using modern databases as i...

Search for neutrino–antineutrino oscillations with a reactor experiment

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. The disappearance of reactor antineutrinos in the Double Chooz experiment is used to investigate the possibility of neutrino-antineutrino oscillations arising due to the breakdown of Lorentz invari-ance. We find no evidence for this phenomenon and set the first limits on 15 coe...

Nuclear reactor safeguards and monitoring with antineutrino detectors

Cubic-meter-sized antineutrino detectors can be used to non intrusively, robustly, and automatically monitor and safeguard a wide variety of nuclear reactor types, including power reactors, research reactors, and plutonium production reactors. Since the antineutrino spectra and relative yields of fissioning isotopes depend on the isotopic composition of the core, changes in composition can be o...

Reactor-based neutrino oscillation experiments

The status of neutrino oscillation searches employing nuclear reactors as sources is reviewed. This technique, a direct continuation of the experiments that proved the existence of neutrinos, is today an essential tool in investigating the indications of oscillations found in studying neutrinos produced in the sun and in the earth’s atmosphere. The low energy of the reactor ̄e makes them ideal ...
