Reactor Experiment for Neutrinos and Exotics (RENE) for the Sterile Neutrino Search Using Reactor Neutrinos

This paper summarizes the details of the Reactor Experiment for Neutrinos and Exotics (RENE). It covers the detector construction, Monte Carlo simulation study, and physics expectations. The primary goal of the RENE project is to investigate the sterile neutrino oscillation at Δm²₄₁ ∼ 2eV², which overlaps with the allowed region predicted by the reactor antineutrino anomaly. On the other hand, the STEREO and PROSPECT experiments have excluded certain regions of the parameter space with 95% confidence level, whereas the joint study conducted by Reactor Experiment for Neutrino Oscillation (RENO) and Neutrino Experiment for Oscillation at Short Baseline (NEOS) suggests possible indications of sterile neutrinos at Δm²₄₁ ∼ 2.4eV² and ∼ 1.7eV² with sin²θ₄₁ < 0.01. Accordingly, a more meticulous investigation of these remaining regions continues to be a scientifically valuable endeavor. This paper reports the technical details of the detector and physics objectives.
