Gonzalez-Garcia 2006 伽玛暴的中微子辐射限定量子引力 2

主要内容:
跟用伽玛光子一样的，也是用不同能量中微子的速度不一样来定量子引力能标下限。

（既然这样，不可以通过光子和中微子的到达时间来做吗？）

Title: Gamma Ray Burst Neutrinos Probing Quantum Gravity
Authors: M.C. Gonzalez-Garcia, F. Halzen
Comments: 14 pages, 2 figures

Very high energy, short wavelength, neutrinos may interact with the space-time foam predicted by theories of quantum gravity. They would propagate like light through a crystal lattice and be delayed, with the delay depending on the energy. This will appear to the observer as a violation of Lorenz invariance. Back of the envelope calculations imply that observations of neutrinos produced by gamma ray bursts may reach Planck-scale sensitivity. We revisit the problem considering two essential complications: the imprecise timing of the neutrinos associated with their poorly understood production mechanism in the source and the indirect nature of their energy measurement made by high energy neutrino telescopes.
