# Monte-Carlo sensitivity study for sterile neutrino search with $^{144}$Ce - $^{144}$Pr source and liquid scintillation detectors of various geometries

## TL;DR

This study uses Monte Carlo simulations to evaluate the sensitivity of various liquid scintillation detector geometries in detecting sterile neutrino oscillations via antineutrino spectra from a $^{144}$Ce-$^{144}$Pr source.

## Contribution

It provides a comparative analysis of detector geometries' sensitivity to sterile neutrino oscillations using detailed Monte Carlo simulations.

## Key findings

- Different detector shapes affect sensitivity to oscillation parameters.
- Simulations indicate optimal geometries for sterile neutrino detection.
- Sensitivity estimates help guide experimental design for sterile neutrino searches.

## Abstract

Expected energy spectra calculations for large volume liquid scintillation detectors to inverse $\beta$-decay for antineutrinos produced by $^{144}$Ce -- $^{144}$Pr artificial source have been performed. The calculations were carried out through Monte-Carlo method within GEANT4.10 framework and were purposed to search for neutrino oscillation to sterile eigenstate with mass about 1 eV. The analysis of relative sensitivity to oscillation parameters for different detector shapes has been performed.
