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 $ u_{e}$ appearance probability with decoherence. The best sensitivity regions found for the decoherence parameters are $Gamma_{21}le 1.2times10^{-23},text{GeV}$ and $Gamma_{32}le 7.7times10^{-25},text{GeV}$ at $90%$ C. L.
We study the physics reach of the long-baseline oscillation analysis of the DUNE experiment when realistic simulations are used to estimate its neutrino energy reconstruction capabilities. Our studies indicate that significant improvements in energy
We investigate the potential for the Deep Underground Neutrino Experiment (DUNE) to probe the existence and effects of a fourth neutrino mass-eigenstate. We study the mixing of the fourth mass-eigenstate with the three active neutrinos of the Standar
If the heaviest neutrino mass eigenstate is unstable, its decay modes could include lighter neutrino eigenstates. In this case part of the decay products could be visible, as they would interact at neutrino detectors via mixing. At neutrino oscillati
In our previous studies (see [1] and references therein) we developed a new theoretical framework that enabled one to consider a new mechanism of neutrino quantum decoherence engendered by the neutrino radiative decay. In parallel, another framework
We explore the capabilities of the upcoming Deep Underground Neutrino Experiment (DUNE) to measure $ u_tau$ charged-current interactions and the associated oscillation probability $P( u_mu to u_tau)$ at its far detector, concentrating on how such re
