“…The proposed liquid argon detector in that experiment is projected to register approximately 10 CEνNS events per kilogram per year, a figure that is suppressed by up to three magnitude orders relative to the projections in the present work. Candidates for reactor-based CEνNS observation include the TEXONO [27,28] and CoGeNT at SONGS projects. All such reactor based environments feature an essentially identical electron antineutrino spectrum.…”

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.

The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) uses low-noise fully depleted charge-coupled devices (CCDs) with the goal of measuring low-energy recoils from coherent elastic scattering (CEνNS) of reactor antineutrinos with silicon nuclei. This standard model process has not yet been observed at recoil energies below 20 keV. We report here the first results of the detector array deployed in 2016, with an active mass of 73.2 g (12 CCDs), which is operating at a distance of 30 m from the core of the Angra 2 nuclear reactor, with a thermal power of 3.8 GW. A search for neutrino events is performed by comparing data collected with reactor on (2.1 kg-day) and reactor off (1.6 kg-day). The results show no excess in the reactor-on data, reaching the world record sensitivity down to recoil energies of about 1 keV (0.1 keV electron-equivalent). A 95% confidence level limit for new physics is established at an event rate of 40 times the one expected from the standard model at this energy scale. The results presented here provide a new window to the low-energy neutrino physics, which allows one to explore for the first time the lowest energies accessible through the CEνNS with antineutrinos from nuclear reactors.

“…By comparison, a nuclear reactor presents an (electron antineutrino) spectral composition distributed across the few MeV range that can exceed all of the solar flux by orders of magnitude, typically 10 12−13 cm −2 s −1 [10,44,45]. This combination presents obvious advantages for the rate of signal events, although it likewise presents new challenges with respect to the management of radiologically intense backgrounds [43].…”

Probing light mediators at ultralow threshold energies with coherent elastic neutrino-nucleus scattering

et al. 2017

Light neutral mediators, with mass 1 GeV, are common features of extensions to the Standard Model (SM). Current astrophysical and terrestrial experiments have constrained the model parameter space, and planned experiments around the world promise continued improvement in sensitivity. In this paper we study the prospects for probing light neutral mediators using terrestrial stopped pion and reactor sources in combination with ultra-low threshold nuclear and electron recoil detectors. We show that the coherent neutrino-nucleus and neutrino-electron scattering channels provide complementary sensitivity to light mediators. With low threshold detectors, we show that most stringent bounds on models arise from the nuclear scattering process, improving upon previous bounds from electron scattering of solar neutrinos by nearly an order of magnitude for mediator masses 0.1 GeV.
