Astrophysical constraints on nonstandard coherent neutrino-nucleus scattering

The exciting possibility of detecting supernova, solar, and atmospheric neutrinos with coherent neutrino-nucleus scattering detectors is within reach, opening up new avenues to probe New Physics. We explore the constraining non-standard through astrophysical neutrinos. Sensitivity bounds on mass coupling mediator are obtained by inspecting modifications induced interaction recoil rate observable in upcoming RES-NOVA DARWIN facilities. Under assumption optimal background tagging, detection from a galactic supernova burst, or one-year exposure solar neutrinos, will place most stringent for couplings $g \gtrsim 10^{-5}$ masses between 1 100 MeV. A similar, but slightly improved, potential COHERENT be provided larger masses. In particular, may potentially provide one order magnitude tighter constraints than XENON1T coupling. Non-standard also force trapped core; this argument allows region parameter space 10^{-4}$, which currently excluded other facilities terrestrial constraints.
