DUNE-Beta: Prospects for a 100-ton scale neutrino-less double-beta decay at DUNE

The DUNE physics program primarily focuses on signals in the GeV energy range. In recent years, DUNE's potential as a low-energy experiment has been explored regarding its sensitivity to signals as low as 5-10 MeV such as those associated with supernova burst and solar neutrinos. I discuss the requirements and modifications that could extend DUNE's sensitivity to energies as low as 2MeV and would enable us to further expand DUNE's physics program to searches for neutrino-less double-beta decay at the multi-ton scale. I will present our proposed modifications with corresponding sensitivity estimates for m/ beta / beta measurements beyond the inverted hierarchy region.
