Description
We study the feasibility of observing deviations from the CPT symmetry owing to quantum decoherence and in the framework of the neutrino oscillations. Taking into account the open system approach, and considering non-diagonal decoherence matrizes, we study all the cases in which CPT violation (CPTV) terms that could be arising in the neutrino oscillation probabilities. Moreover, and based on the information from the muon neutrino/antineutrino channels, we put on trial all the CPTV cases using the DUNE experiment. For the optimal case, we find 5 $\sigma$ of confidence for $\Gamma (E / \mathrm{GeV})^{n} \sim 13.1 \times 10 ^{-23} \mathrm{GeV}$, $4.6 \times 10 ^{-23} \mathrm{GeV}$ $2.1 \times 10 ^{-23} \mathrm{GeV}$ y $0.8 \times 10 ^{-23} \mathrm{GeV}$ for $n = -1$, 0, 1 and 2 respectively.
