Light and Charge Calorimetries for Enhanced CP Violation and Mass Hierarchy Sensitivities in DUNE
摘要
This study investigate the feasibility of light calorimetry in liquid argon time projection chambers (LArTPCs) and its intrinsic self-compensation effects, highlighting its benefits relative to well-established charge calorimetry. Light calorimetry has been shown to attain an energy resolution comparable to cutting-edge charge-based techniques [1], with GeV neutrinos serving as a benchmark. We evaluate how light calorimetry, when employed independently, complements charge calorimetry in improving precision measurements of key neutrino oscillation parameters, particularly in CP violation and mass hierarchy studies at DUNE.
