“…In contrast to the case of the stopped-pion source, reactor-based experiments are only sensitive to the mixing of the electron neutrino with the sterile state. Finally, CEνNS has been proposed as a new probe of lepton unitarity and sterile neutrinos [131,132].…”

Coherent elastic neutrino-nucleus scattering (CEνNS) is a process in which neutrinos scatter on a nucleus which acts as a single particle. Though the total cross section is large by neutrino standards, CEνNS has long proven difficult to detect, since the deposited energy into the nucleus is ∼ keV. In 2017, the COHERENT collaboration announced the detection of CEνNS using a stopped-pion source with CsI detectors, followed up the detection of CEνNS using an Ar target. The detection of CEνNS has spawned a flurry of activities in high-energy physics, inspiring new constraints on beyond the Standard Model (BSM) physics, and new experimental methods. The CEνNS process has important implications for not only high-energy physics, but also astrophysics, nuclear physics, and beyond. This whitepaper discusses the scientific importance of CEνNS, highlighting how present experiments such as COHERENT are informing theory, and also how future experiments will provide a wealth of information across the aforementioned fields of physics.

“…By comparing the measured NC flux to the theoretical prediction we can hence obtain constraints on tau neutrinos. 19 From [91] using the standard solar model the theoretical expectation for the 8 Be flux is (A.30) 18 It has been shown in [89] that a careful statistical treatment is necessary to obtain robust constraints on new physics parameters. This conclusion was derived for the example of non standard interactions.…”

The tau neutrino is the least well measured particle in the Standard Model. Most notably, the tau neutrino row of the lepton mixing matrix is quite poorly constrained when unitarity is not assumed. In this paper we identify several new and overlooked data sets involving tau neutrinos that improve our understanding of the tau neutrino part of the mixing matrix. We present new results on the unitarity of the tau row leveraging existing constraints on the electron and muon rows for the cases of unitarity violation, with and without kinematically accessible steriles. We also show the expected sensitivity due to upcoming experiments and demonstrate that the tau neutrino row precision is expected to be comparable to the muon neutrino row in a careful combined fit.

“…Before embarking to the nuclear physics calculations, it is worth mentioning that, interesting studies of physics beyond the standard model include deviations from unitarity [42], sterile neutrinos [42][43][44], neutrino magnetic moments [45][46][47], nonstandard interactions [30,32,48,49], light new physics [29,50], dark matter [51,52], etc.…”

Realistic nuclear structure calculations are presented for the event rates due to coherent elastic neutrino-nucleus scattering (CEνNS), assuming neutrinos from pion-decay at-rest, from nuclear reactors and from Earth's interior. We focus on the currently interesting Germanium isotopes, 70,73,76 Ge, which constitute detector materials of the recently planned CEνNS experiments. We study in addition the potential use of 64,70 Zn and 28 Si isotopes as promising CEνNS detectors. From nuclear physics perspectives, recently, calculations have been carried out within the framework of the deformed shell-model (DSM), based on realistic nuclear forces, and assessed on the reproducibility of spectroscopic nuclear properties. The high confidence level acquired by their agreement with experimental results and by their comparison with other mostly phenomenological calculations encouraged the use of DSM to extract predictions for the CEνNS event rates of the above isotopes. Our detailed estimation of the nuclear physics aspects of the recently observed neutral current coherent neutrino-nucleus scattering may shed light on unravelling the still remaining uncertainties for the CEνNS process within and beyond the Standard Model.
