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 the Deep Underground Neutrino Experiment as a case study, we performed sensitivity analyses for two neutrino flux configurations, finding sensitivity limits for the decoherence parameters. We also offer a physical interpretation for a new peak which arises at the \ensuremathν_e appearance probability with decoherence. The sensitivity limits found for the decoherence parameters are \mathrm\ensuremathΓ₂₁\ensuremath≤1.2\ifmmode×\else\texttimes\fi10^\ensuremath-23 GeV and \mathrm\ensuremathΓ₃₂\ensuremath≤7.7\ifmmode×\else\texttimes\fi10^\ensuremath-25 GeV at 90% C.L.
