“…The instantaneous thermal power of each reactor core is provided by EDF with time steps of < 1 minute with an uncertainty of 0.5 % at the full reactor power.ν e 's are produced in nuclear reactors by the β-decay of fission products, in which more than 99.7 % of fissions originate from four isotopes, 235 U, 239 Pu, 238 U, and 241 Pu. The referenceν e spectra are derived for 235 U, 239 Pu and 241 Pu from fits to their β spectrum measured at the ILL research reactor [14][15][16] considering the allowed transitions. It was highlighted that contribution of the forbidden - Table 1.…”

“…Estimated background rates are summarized in table 4 including contributions from other background sources not used in the neutrino oscillation fit. The background rate of 13 C(α, n) 16 O reactions is evaluated from the contamination of α emitters (including 152 Gd) in the detector to be well below 0.1 events/day. 12 B events are produced from 12 C in the detector either through an (n, p) reaction with spallation neutrons or a (µ − , ν µ ) reaction with cosmic muons, and then β − decay with a lifetime of 29.1 ms and a Q-value of 13.4 MeV.…”

Abstract: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 235 U reactor antineutrino flux and at 2.5σ with respect to variations of the 235 U and 239 Pu 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 235 U flux at 3.1σ and variations of the 235 U and 239 Pu fluxes at 2.8σ. We also found that both the Daya Bay evolution data and the global rate data are well-fitted with composite hypotheses including variations of the 235 U or 239 Pu fluxes in addition to active-sterile neutrino oscillations. A combined analysis of the Daya Bay evolution data and the global rate data shows a slight preference for oscillations with respect to variations of the 235 U and 239 Pu fluxes. However, the best fits of the combined data are given by the composite models, with a preference for the model with an enhancement of the 239 Pu flux and relatively large oscillations.

“…A classic series of reactor experiments and analyses [16,18,20,21] performed during the 1980's are the standing primary references for numbers on the normalization and detailed spectral distribution of neutrino daughter products; a more recent reinterpretation of the historical data was presented in Ref. [22].…”

Sensitivity toZ-prime and nonstandard neutrino interactions from ultralow threshold neutrino-nucleus coherent scattering

We discuss prospects for probing Z-prime and non-standard neutrino interactions using neutrinonucleus coherent scattering with ultra-low energy (∼ 10 eV) threshold Si and Ge detectors. The analysis is performed in the context of a specific and contemporary reactor-based experimental proposal, developed in cooperation with the Nuclear Science Center at Texas A&M University, and referencing available technology based upon economical and scalable detector arrays. For expected exposures, we show that sensitivity to the Z-prime mass is on the order of several TeV, and is complementary to the LHC search with low mass detectors in the near term. This technology is also shown to provide sensitivity to the neutrino magnetic moment, at a level that surpasses terrestrial limits, and is competitive with more stringent astrophysical bounds. We demonstrate the benefits of combining silicon and germanium detectors for distinguishing between classes of models of new physics, and for suppressing correlated systematic uncertainties.
