Query: Probing light mediators at ultra-low threshold energies with coherent
  elastic neutrino-nucleus scattering   Light neutral mediators, with mass $\lesssim 1$ GeV, are common features of
extensions to the Standard Model (SM). Current astrophysical and terrestrial
experiments have constrained the model parameter space, and planned experiments
around the world promise continued improvement in sensitivity. In this paper we
study the prospects for probing light neutral mediators using terrestrial
stopped pion and reactor sources in combination with ultra-low threshold
nuclear and electron recoil detectors. We show that the coherent
neutrino-nucleus and neutrino-electron scattering channels provide
complementary sensitivity to light mediators. With low threshold detectors, we
show that most stringent bounds on models arise from the nuclear scattering
process, improving upon previous bounds from electron scattering of solar
neutrinos by nearly an order of magnitude for mediator masses $\gtrsim 0.1$
GeV.
