Energy Reconstruction of Michel Electron Spectrum for the Eos Hybrid Neutrino Detector

Michel electrons, produced in the decay of stopped muons, provide a well-defined energy spectrum of high-energy electrons between 10 to 50 MeV. Eos is a 20-tonne hybrid Cherenkov/scintillation neutrino detector that will be used to explore the performance of different detector configurations, including a range of novel scintillators, such as Water-based Liquid Scintillator (WbLS). Eos is currently positioned near the surface to understand backgrounds for potential deployment at a neutrino source. This presentation will cover the modeling of the Michel spectrum using Monte Carlo and will demonstrate how this approach reproduces the Eos data. A simple energy reconstruction method will also be discussed. In the future, this method can be used to compare with more advanced approaches, such as Machine Learning methods.
