A Search for Sterile Neutrino Oscillations with PROSPECT

O. Kyzylova, Drexel University, for the PROSPECT Collaboration

The Precision Reactor Oscillation and Spectrum Experiment (PROSPECT) makes a precision measurement of antineutrinos from the High Flux Isotope Reactor (HFIR) through inverse beta decay at a baseline range of 7-9 m from the reactor core. The single, movable detector consists of 154 optically separated individual segments filled with ⁶Li-loaded liquid scintillator. The detector segments aid with the event localization and cover a range of baselines from the reactor core. The segmented detector design allows a reactor-model independent search for eV²-scale sterile neutrino oscillations by performing a relative measurement of the antineutrino event rates and energy distributions between segments within the detector. This talk will discuss the PROSPECT oscillation analysis and present recent results.
