Quantum Decoherence Effects in Neutrino Oscillations at DUNE

Abstract

In this work we analyze quantum decoherence in neutrino oscillations considering the Open Quantum System framework and oscillations through matter for three neutrino families. Taking DUNE as a case study we performed sensitivity analyses for two neutrino flux configurations finding limits for the decoherence parameters. We also offer a physical interpretation for a new peak which arises at the ${\nu }_e$ appearance probability with decoherence. The best sensitivity regions found for the decoherence parameters are ${\Gamma }_{21}\le 1.2\times 10^{-23}\text{GeV}$ and ${\Gamma }_{32}\le 7.7\times 10^{-25}\text{GeV}$ at $90\%$ C. L.
