abstract

Solar neutrinos induce elastic neutrino-electron scattering in dark matter direct detection experiments, resulting in detectable event rates at current facilities. We analyze recent data from the XENONnT, LUX-ZEPLIN, and PandaX-4T experiments and we derive stringent constraints on several $U(1)'$ extensions of the Standard Model, accommodating new neutrino-electron interactions. We provide bounds on the relevant coupling and mass of light vector mediators for a variety of models, including the anomaly-free $B-L$ model, lepton flavor-dependent interactions like $L_\alpha - L_{\beta}$, $B-2L_e - L_{\mu, \tau}$, $B-3L_\alpha$, and $B+2L_\mu +2 L_{\tau}$ models. We compare our results with other limits obtained in the literature from both terrestrial and astrophysical experiments. Finally, we present forecasts for improving current bounds with a future experiment like DARWIN.

  1. Neutrino electromagnetic properties and sterile dipole portal in light of the first solar CE$\nu$NS data

    hep-ph 2024-12 conditional novelty 6.0 of 10

    The paper derives the first 90% CL limits on neutrino magnetic moments, millicharges, and the sterile dipole portal from solar 8B CEνNS data in XENONnT and PandaX-4T.

  2. $\texttt{SNuDD}$: Solar Neutrinos for Direct Detection

    hep-ph 2026-07 conditional novelty 5.0 of 10

    SNuDD computes solar-neutrino recoil spectra with non-standard interactions and derives NSI limits from xenon direct-detection data that are competitive with dedicated neutrino experiments.

  3. Testing light and heavy vector mediators with solar CE$\nu$NS measurements

    hep-ph 2026-02 conditional novelty 5.0 of 10

    Combined solar CEνNS data from XENONnT, PandaX-4T, and LZ yield competitive constraints on vector NSI and light mediators and a weak mixing angle measurement at low momentum transfer.

  4. New light mediators and the neutrino fog: Implications from XENONnT nuclear recoil data

    hep-ph 2025-12 conditional novelty 5.0 of 10

    Light-mediator couplings are constrained more strongly when they attach to dark matter than to neutrinos, and the neutrinofog in xenon detectors is shifted and deformed under both scenarios.

    hep-ph 2025-01 conditional novelty 5.0 of 10

    CONUS+ and TEXONO reactor CEνNS data are consistent with the Standard Model and yield the most stringent limit on the electron neutrino millicharge through neutrino-electron scattering.

  6. Probing Standard Model and Beyond with Reactor CE$\nu$NS Data of CONUS+ experiment

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Using CONUS+ reactor data, the authors constrain the weak mixing angle, neutrino electromagnetic properties, and light scalar and vector mediators, finding their most notable limit on neutrino millicharge when electro...

  7. Probing conventional and new physics at the ESS with coherent elastic neutrino-nucleus scattering

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Projected ESS CEνNS measurements would improve current constraints on the weak mixing angle, nuclear neutron radii, and several new physics scenarios by large factors, and would lead in some unexplored mass ranges.
