Exploring the nature of neutrinos in a dissipative environment

Abstract In this study, we explore the scope of determining the neutrino nature in long-baseline neutrino oscillation experiments considering the effect of environmental decoherence in neutrino evolution. Assuming an open quantum system framework, we numerically analyze the two flavor neutrino oscillation probabilities. We observe that the transition probabilities accommodate the Majorana phase in the presence of dissipative environment. Considering this phenomenology, we study the effect of Majorana phase on these probabilities and investigate the sensitivity of T2K, ESSnuSB, NOvA, T2HKK and DUNE to differentiate between Dirac and Majorana neutrinos.
