标题： Constraints on relativity violations from gamma-ray bursts

摘要： 相对论的洛伦兹对称性以及相关的离散CPT对称性的微小违反可能在一个自洽的量子引力理论（如弦理论）中出现。 伽马射线暴中近期关于线性偏振的证据将涉及光子的洛伦兹和CPT对称性破缺的灵敏度提高了几个数量级，提高因子从十到百万不等。 显示英文摘要

摘要： Tiny violations of the Lorentz symmetry of relativity and the associated discrete CPT symmetry could emerge in a consistent theory of quantum gravity such as string theory. Recent evidence for linear polarization in gamma-ray bursts improves existing sensitivities to Lorentz and CPT violation involving photons by factors ranging from ten to a million.
