| contents | We investigate the potential of light calorimetry in liquid argon time projection chambers and its intrinsic self compensation properties, emphasizing its advantages alongside conventional charge calorimetry. Previous studies have demonstrated that light calorimetry can achieve energy resolution comparable to advanced charge based techniques, particularly for GeV scale neutrinos. In this work, we explore the complementarity of light calorimetry with charge calorimetry for precision measurements of key physics parameters in the DUNE, including CP violation (CPV) and mass hierarchy determination. While charge calorimetry provides superior resolution in CP phase measurements, light calorimetry independently offers significant insights into CPV and mass hierarchy sensitivities. Furthermore, our exposure versus CPV sensitivity studies indicate that the $5σ$ discovery potential is reached faster using light and charge calorimetry than with the traditional TDR based reconstruction methods. These findings highlight the promising role of light calorimetry as a simple yet effective reconstruction method, serving as a complementary approach to enhance the physics capabilities of DUNE. |
