abstract
The coherent elastic scattering of neutrinos off nuclei has eluded detection for four decades, even though its predicted cross-section is the largest by far of all low-energy neutrino couplings. This mode of interaction provides new opportunities to study neutrino properties, and leads to a miniaturization of detector size, with potential technological applications. We observe this process at a 6.7-sigma confidence level, using a low-background, 14.6-kg CsI[Na] scintillator exposed to the neutrino emissions from the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. Characteristic signatures in energy and time, predicted by the Standard Model for this process, are observed in high signal-to-background conditions. Improved constraints on non-standard neutrino interactions with quarks are derived from this initial dataset.

CONNIE's first Skipper-CCD run at Angra-2 yields no CEνNS excess, comparable prior limits on neutrino rates, improved bounds on light vector mediators, and record surface DM-electron limits via diurnal modulation.
Cryogenic pure CsI converts the suppression of nuclear recoil ionization into a selective probe for neutrino-electron scattering, enabling better constraints on neutrino electromagnetic couplings at reactor sites.
Neutral-current events supply sensitivity to isovector NSI parameters that charged-current analyses suppress, enabling the first bounded long-baseline constraints and resolution of individual quark couplings when the two datasets are combined.
Computes the diffuse UHECR-boosted CνB flux across elastic, coherent, incoherent, resonance, and deep-inelastic channels with mixed-composition UHECR models and derives upper limits on CνB overdensity from IceCube and Auger data.
Coherent enhancement in detectors is quantitatively constrained by single-mode entanglement entropy, with general bounds on scaling with system size that interpolate between incoherent and fully coherent regimes.
XENONnT measures solar 8B neutrino coherent scattering at 3.3 sigma, finds no light dark matter, and constrains the weak mixing angle at low momentum transfer.
Proposes a hydrocarbon detector at SNS for order-of-magnitude better sensitivity to 10-100 MeV axion-like particles and heavy neutral leptons via e+e- decays from muon decays at rest.
New reactor antineutrino data from CONUS germanium detectors improve upper limits on neutrino magnetic moment to 5.18e-11 mu_B, millicharge to 1.76e-12 e0, NSI scale to 145 GeV, and yield sin^2 theta_W = 0.28 +0.03/-0.04 at ~10 MeV.
Reactor neutrino data from CONUS+ and Dresden-II combined with COHERENT and IceCube data singles out a region of neutrino and nuclear couplings consistent with the X17 particle.
Relating two GNI parametrizations shows scalar neutrino-quark interactions are more tightly constrained by COHERENT while tensor interactions are better bounded by deep inelastic scattering.
High-statistics CEνNS measurements at J-PARC are feasible with significant sensitivity to relevant particle physics scenarios using currently funded detectors.
Statistical analysis of CONUS+ CEvNS data constrains NSI and NGI from light vector bosons in E6 and U(1)Le-Lμ frameworks.
Antineutrino-based detection can function as a barrier for locating nuclear submarines, with a 20 kt detector achieving Z_A ≈ 2.54 in the Strait of Gibraltar for a 100 MW case and higher scores with multiple detectors.
