Title: NEOS Data and the Origin of the 5 MeV Bump in the Reactor Antineutrino Spectrum

Abstract

We perform a combined analysis of recent NEOS and Daya Bay data on the reactor antineutrino spectrum. This analysis includes approximately 1.5 million antineutrino events, which is the largest neutrino event sample analyzed to date. We use a double ratio which cancels flux model dependence and related uncertainties as well as the effects of the detector response model. We find at 3–4 standard deviation significance level, that plutonium-239 and plutonium-241 are disfavored as the single source for the so-called 5 MeV bump. This analysis method has general applicability and, in particular, with higher statistics data sets, will be able to shed significant light on the issue of the bump. With some caveats, this should also allow us to improve the sensitivity for sterile neutrino searches in NEOS.

Particle physics origin of the 5 MeV bump in the reactor antineutrino spectrum?

Journal Article Berryman, Jeffrey M. ; Brdar, Vedran ; Huber, Patrick - Physical Review D

One of the most puzzling questions in neutrino physics is the origin of the excess at 5 MeV in the reactor antineutrino spectrum. In this paper, we explore the excess via the reaction ¹³C(v¯,v¯'n)¹²C(*) in organic scintillator detectors. The deexcitation of ¹²C(*) yields a prompt 4.4 MeV photon, while the thermalization of the product neutron causes proton recoils, which in turn yield an additional prompt energy contribution with finite width. Together, these effects can mimic an inverse beta decay event with around 5 MeV energy. We consider several nonstandard neutrino interactions to produce such a process and find that themore »« less

Reactor fuel fraction information on the antineutrino anomaly

We analyzed the evolution data of the Daya Bay reactor neutrino experiment in terms of short-baseline active-sterile neutrino oscillations taking into account the theoretical uncertainties of the reactor antineutrino fluxes. We found that oscillations are disfavored at 2.6σ with respect to a suppression of the ²³⁵U reactor antineutrino flux and at 2.5σ with respect to variations of the ²³⁵U and ²³⁹Pu fluxes. On the other hand, the analysis of the rates of the short-baseline reactor neutrino experiments favor active-sterile neutrino oscillations and disfavor the suppression of the ²³⁵U flux at 3.1σ and variations of the ²³⁵U and ²³⁹Pu fluxes atmore »« less

Diagnosing the reactor antineutrino anomaly with global antineutrino flux data

We have examined the impact of new Daya Bay, Double Chooz, and RENO measurements on global fits of reactor antineutrino flux data to a variety of hypotheses regarding the origin of the reactor antineutrino anomaly. In comparing RENO and Daya Bay measurements of inverse beta decay (IBD) yield versus ²³⁹Pu fission fraction, we find differing levels of precision in measurements of time-integrated yield and yield slope, but similar central values, leading to modestly enhanced isotopic IBD yield measurements in a joint fit of the two datasets. In the absence of sterile neutrino oscillations, global fits to all measurements now providemore »« less

Dissecting Reactor Antineutrino Flux Calculations

Journal Article Sonzogni, A. A. ; McCutchan, E. A. ; Hayes, A. C. - Physical Review Letters

Current predictions for the antineutrino yield and spectra from a nuclear reactor rely on the experimental electron spectra from ²³⁵ U , ²³⁹ Pu , ²⁴¹ Pu and a numerical method to convert these aggregate electron spectra into their corresponding antineutrino ones. In our present work we investigate quantitatively some of the basic assumptions and approximations used in the conversion method, studying first the compatibility between two recent approaches for calculating electron and antineutrino spectra. We then explore different possibilities for the disagreement between the measured Daya Bay and the Huber-Mueller antineutrino spectra, including the ²³⁸ U contribution as wellmore »« less
