Abstract
Motivated by the quantum structure of space-time at high scales M QG, we study the propagation behavior of the high-energy neutrino within the quantum gravity effect. We consider the possible induced dispersive effect and derive the resulting vacuum refraction index ηvac(E ν) ≃ 1 + E 2ν /M 2QG . Then, by referring to the SN1987A and basing on the recorded neutrino data we approach the corresponding scale M QG ≃ 104 GeV.
