Possible cosmogenic neutrino constraints on Planck-scale Lorentz violation

David M. Mattingly, Luca Maccione, Matteo Galaverni +2

We study, within an effective field theory framework, $O(E^{2}/\Mpl^{2})$ Planck-scale suppressed Lorentz invariance violation (LV) effects in the neutrino sector, whose size we pa…
