Precision $\bar ν_e$-electron Scattering Measurements with IsoDAR to Search for New Physics

Abstract: IsoDAR provides a pure and intense $\bar \nu_e$ source with an average energy of 6.5 MeV produced through $^8$Li $\beta$-decay. This source can be paired with a large scintillator detector, such as KamLAND, to produce a sample of $\bar \nu_e$-electron scatters that is more than five times larger than what has been collected before. Such a sample would allow for a 3.2% measurement of $\sin^2\theta_W$ and a sensitive search for non-standard interactions.
