“…extracted in Ref. [102]. On the other hand, an improved determination of the CsI[Na] quenching factor can in principle lead to a significantly better agreement between the experimental results and the theoretical simulations [103], as well as to an improved sensitivity on the weak mixing angle [78].…”

We review standard and non-standard neutrino physics probes that are based on nuclear measurements. We pay special attention on the discussion of prospects to extract new physics at prominent rare event measurements looking for neutrino-nucleus scattering, such as the coherent elastic neutrino-nucleus scattering (CEνNS) that may involve lepton flavor violation (LFV) in neutralcurrents (NC). For the latter processes several appreciably sensitive experiments are currently pursued or have been planed to operate in the near future, like the COHERENT, CONUS, CONNIE, MINER, TEXONO, RED100, vGEN, Ricochet, NUCLEUS etc. We provide a thorough discussion on phenomenological and theoretical studies, in particular those referring to the nuclear physics aspects in order to provide accurate predictions for the relevant experiments. Motivated by the recent discovery of CEνNS at the COHERENT experiment and the active experimental efforts for a new measurement at reactor-based experiments, we summarize the current status of the constraints as well as the future sensitivities on nuclear and electroweak physics parameters, non-standard interactions, electromagnetic neutrino properties, sterile neutrinos and simplified scenarios with novel vector Z or scalar φ mediators. Indirect and direct connections of CEνNS with astrophysics, direct Dark Matter detection and charge lepton flavor violating processes are also discussed.

“…The difficulty is that it is necessary to observe nuclear recoils with very small kinetic energy T , smaller than a few keV, in order to satisfy the coherence requirement | q|R 1 [23], where | q| √ 2M T is the three-momentum transfer, R is the nuclear radius of a few fm, and M is the nuclear mass, of the order of 100 GeV for heavy nuclei. The observation of coherent elastic neutrino-nucleus scattering opens up a new and powerful way to probe the properties of nuclei, neutrinos, weak interactions, and new physics beyond the Standard Model [24][25][26][27][28][29][30][31][32]. Indeed, the first measurements of the CO-HERENT experiment have already produced interesting results for nuclear physics [33], neutrino properties and interactions [17,[34][35][36][37], and weak interactions [38].…”

Neutrino charge radii from COHERENT elastic neutrino-nucleus scattering

et al. 2018

Coherent elastic neutrino-nucleus scattering is a powerful probe of neutrino properties, in particular of the neutrino charge radii. We present the bounds on the neutrino charge radii obtained from the analysis of the data of the COHERENT experiment. We show that the time information of the COHERENT data allows us to restrict the allowed ranges of the neutrino charge radii, especially that of νµ. We also obtained for the first time bounds on the neutrino transition charge radii, which are quantities beyond the Standard Model.

“…where g n V = − 1 2 and g n V = 1 2 − 2 sin 2 θ W are the weak vector charges of the proton and neutron, respectively, with Weinberg angle θ W . At low energies in the MS scheme, sin 2 θ W ≈ 0.23 [144][145][146], meaning that the weak vector charge of the proton is nearly zero.…”

We explore the complementarity between terrestrial neutrino oscillation experiments and astrophysical/cosmological measurements in probing the existence of sterile neutrinos. We find that upcoming accelerator neutrino experiments will not improve on constraints by the time they are operational, but that reactor experiments can already probe parameter space beyond the reach of Planck. We emphasize the tension between cosmological experiments and reactor antineutrino experiments and enumerate several possibilities for resolving this tension. † It is, by hypothesis, not possible to directly detect sterile neu-arXiv:1905.03254v1 [hep-ph]
