Ultra-high-energy tau neutrino detections at GRAND and POEMMA are projected to constrain Lorentz invariance violation parameters orders of magnitude more stringently than current lower-energy probes.
Assuming the KM3-230213A event comes from heavy dark matter decay, the preferred mass exceeds 100 PeV at 95% CL with lifetimes of 10^26-10^27 s, but these regions conflict with bounds from other neutrino telescopes and gamma-ray observations.
