Description
The physics programs of LArTPCs primarily focus on signals in the GeV energy range. In recent years, the potential for LArTPCs as a low-energy experiment has been fruitfully explored, specifically regarding its sensitivity to signals as low as 5-10 MeV such as those associated with supernova burst and solar neutrinos in DUNE. In this presentation, we will discuss the requirements and modifications that could extend a DUNE-like detector to energies to the MeV-scale and could enable us to further expand DUNE's physics program to searches for neutrino-less double-beta decay in xenon-doped liquid argon TPC at the multi-kiloton scale. I will present the modifications we propose with corresponding sensitivity estimates for the effective Majorana mass measurements beyond the inverted hierarchy region, and describe the rich and diverse R&D program that this research avenue would open.
