OscSNS: A Precision Short-Baseline Neutrino Oscillation Experiment

Short baseline neutrino experiments are consistent with neutrino oscillations at a $\Delta m^2$ of approximately 1 eV$^2$, and world neutrino and antineutrino data fit reasonably well to a 3+2 (active+sterile) neutrino oscillation model with CP violation. The OscSNS experiment at ORNL would be able to make precision short-baseline neutrino oscillation measurements and prove that sterile neutrinos exist. The OscSNS experiment will be described and the corresponding neutrino oscillation sensitivities will be discussed.
