Unearthing Neutrino Decoherence from Quantum Spacetime: An Open Quantum Systems Perspective

Abstract

We investigated the influence of \(κ\) Minkowski-type quantum spacetime on neutrino oscillations, revealing that spacetime fluctuations introduce a unique energy-dependent power law, \(E^{-4}\), in the decoherence effect for relic neutrinos. This effect is particularly pronounced for low-energy neutrinos, such as those from the cosmic neutrino background ($C\hat{I}½B$). Our results indicate the potential for new models of low-energy quantum gravity-induced decoherence, which could pave the way for future experiments, such as IceCube-Gen2 and KM3NeT, to further constrain the deformation parameter.

Due to the inclusion of additional authors and to prevent any potential confusion for readers, we have decided to withdraw this version
