Monolithic liquid scintillator detectors are searching for neutrinoless double beta decay, a theorized process that would confirm the Majorana nature of neutrinos. The production and propagation of photons in the detection medium depend on various optical properties, such as light yield, attenuation lengths and re-emission/absorption spectra. These must all be separately characterized,...
Accurate characterization of scintillation emission profiles is essential for robust event reconstruction in liquid scintillator detectors. The SNO+ Collaboration has developed an innovative framework employing Bayesian optimization (BO) to calibrate these timing profiles using internal radioactive backgrounds. Our results demonstrate that BO achieves convergence in at least an order of...
Detector simulation in liquid argon time projection chambers (LArTPCs) is a constant challenge. In particular the modeling of electrons response on wires is highly nontrivial. However, new machine learning techniques exist which can be leveraged to ameliorate these concerns. We present a novel methodology to attempt to learn from cosmic muon data in the ICARUS detector how reconstructed wire...
The Reactor Experiment for Neutrinos and Exotics (RENE) is a pioneering initiative aimed at investigating the existence of sterile neutrinos within the Δm²≈2 eV² parameter space, motivated by the observed Reactor Antineutrino Anomaly. The experimental setup consists of a cylindrical target volume containing 270 liters of gadolinium-loaded liquid scintillator (Gd-LS), surrounded by a...
