Neutrino Physics Opportunities with the IsoDAR Source at Yemilab

IsoDAR seeks to place a high-power-cyclotron and target combination, as an intense source of (nu) over bar (e) at the level of similar to 10(23)/year, close to a kiloton-scale neutrino detector in order to gain sensitivity to very short-baseline neutrino oscillations ((nu) over bar (e )-> (nu) over bar (e)) and perform precision tests of the weak interaction, among other physics opportunities. Recently, IsoDAR has received preliminary approval to be paired with the 2.26 kton target volume liquid scintillator detector at the Yemi Underground Laboratory (Yemilab) in Korea, at a 17 m center-to-center baseline, and cavern excavation for IsoDAR is now complete. In this paper, we present the physics capabilities of IsoDAR@Yemilab in terms of sensitivity to oscillations (via inverse beta decay, IBD; (nu) over bar (e )+ p -> e(+) + n), including initial-state wave packet effects, and the weak mixing angle (via elastic scattering off atomic electrons, (nu) over bar (e )+ e(- )-> (nu) over bar (e) + e(-)). We also introduce a study of IsoDAR sensitivity to new particles, such as a light X boson, produced in the target that decays to nu(e)(nu) over bar (e).
