# Constraining Sterile Neutrino Interpretations of the LSND and MiniBooNE Anomalies with Coherent Neutrino Scattering Experiments

## TL;DR

This paper proposes using coherent neutrino scattering experiments to test sterile neutrino interpretations of LSND and MiniBooNE anomalies, offering a new method to measure neutrino fluxes and constrain sterile neutrino parameters.

## Contribution

It introduces a novel experimental approach using coherent neutrino scattering to independently measure neutrino fluxes and constrain sterile neutrino models related to LSND and MiniBooNE anomalies.

## Key findings

- A 100 kg CsI detector can probe significant sterile neutrino parameter space.
- Timing and baseline measurements reduce systematic uncertainties.
- The method can distinguish active neutrino flavors in flux measurements.

## Abstract

Results from the LSND and MiniBooNE experiments have been interpreted as evidence for a sterile neutrino with a mass near the electronvolt scale. Here we propose to test such a scenario by measuring the coherent elastic scattering rate of neutrinos from a pulsed spallation source. Coherent scattering is universal across all active neutrino flavors, and thus can provide a measurement of the total Standard Model neutrino flux. By performing measurements over different baselines and making use of timing information, it is possible to significantly reduce the systematic uncertainties and to independently measure the fluxes of neutrinos that originate as $\nu_{\mu}$ or as either $\nu_e$ or $\bar{\nu}_{\mu}$. We find that a 100 kg CsI detector would be sensitive to the large fraction of the sterile neutrino parameter space that could potentially account for the LSND and MiniBooNE anomalies.
