Precisionν¯e-electron scattering measurements with IsoDAR to search for new physics

Abstract

IsoDAR provides a pure and intense ${\overline{\nu }}_e$ source with an average energy of 6.5 MeV produced through ${}^8\mathrm{Li}$ $\beta$ decay. This source can be paired with a large scintillator detector, such as KamLAND, to produce a sample of ${\overline{\nu }}_e$-electron scatters that is more than 5 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 nonstandard interactions.
