Precision $\bar{\hat{I}}{½}_e$-electron Scattering Measurements with IsoDAR to Search for New Physics

Abstract

IsoDAR provides a pure and intense $\bar{\hat{I}}{½}_e$ source with an average energy of 6.5 MeV produced through ${}^8$Li ${\hat{I}}^2$-decay. This source can be paired with a large scintillator detector, such as KamLAND, to produce a sample of $\bar{\hat{I}}{½}_e$-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 ${\sin }^2\hat{I}{¸}_W$ and a sensitive search for non-standard interactions.
