| contents | 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 ($CνB$). 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. |
