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 Lα– Lβ, B – 2Le– Lμ,τ, B – 3Lα, and B + 2Lμ + 2Lτ 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.

“…This can happen if the new contributions to the neutrino matter potential δV a from the oscillating A field are still significant at the present time. We will present an exhaustive study in the future [110]; here we make a preliminary investigation to show that there is no conflict with the allowed region in figure 6.…”

Sterile neutrinos (νs) that mix with active neutrinos (νa) are interesting dark matter candidates with a rich cosmological and astrophysical phenomenology. In their simplest incarnation, their production is severely constrained by a combination of structure formation observations and X-ray searches. We show that if active neutrinos couple to an oscillating condensate of a very light L μ-L τ gauge field, resonant νa-νs oscillations can occur in the early universe, consistent with νs constituting all of the dark matter, while respecting X-ray constraints on νs→νaγ decays. Interesting deviations from standard solar and atmospheric neutrino oscillations can persist to the present.

“…Therefore, at resonance eq. where we use g ′ f f ∼ 3.63 × 10 −24 , m ′ A ∼ 1.02 × 10 −14 eV [26]. For x res = 1, η = 6.40 × 10 −12 and ϵ does not admit a real solution.…”

“…Several tests of gravity in the solar system scale obtain interesting constraints on UVDM and USDM [15][16][17][18][19][20][21][22][23][24]. They can also be probed from the neutrino oscillation experiments [25][26][27]. The ultralight (pseudo) scalar particles such as axion, majoron, dilaton and the ultralight vector particles such as L i − L j vector gauge boson, dark photon are the potential DM candidates.…”

The interaction of neutrinos with ultralight scalar and vector dark matter backgrounds induce a modification of the neutrino dispersion relation. The effects of this modification are reviewed in the framework of asymmetric emission of neutrinos from the supernova core, and, in turn, of pulsar kicks. We consider the neutrino oscillations, focusing in particular to active-sterile conversion. The ultralight dark matter induced neutrino dispersion relation contains a term of the form δ Ω · p̂, where δ Ω is related to the ultralight dark matter field and p̂ is the unit vector along the direction of neutrino momentum. The relative orientation of p with respect to δ Ω affects the mechanism for the generation of the observed pulsar velocities. We obtain the resonance condition for the active-sterile neutrino oscillation in ultralight dark matter background and calculate the star parameters in the resonance surface so that both ultralight scalar and vector dark matter backgrounds can explain the observed pulsar kicks. The asymmetric emission of neutrinos in presence of ultralight dark matter background results gravitational memory signal which can be probed from the future gravitational wave detectors such as adLIGO (advanced LIGO), adVIRGO (advanced VIRGO), DECIGO (DECi-hertz Interferometer Gravitational wave Observatory), BBO (Big Bang Observer), and ET (Einstein Telescope). We also establish a relation between the ultralight dark matter parameters and the Lorentz and CPT invariance violation parameters.
