用费米约束Lorentz破坏

Constraining Lorentz Violation with Fermi

Vlasios Vasileiou

摘要:

狭义相对论的基石之一是假设所有的观察者都测量到完全相同的光子速度,而与光子能量无关。然而,一个假设的时空结构可能会在超小尺度上改变这一结论。通过对伽马射线暴光变曲线中的尖锐特征进行高时间分辨率的测量,在宇宙学的光旅行时间中积累起来,即使是光速中微小的能量依赖性变化也可能被揭示出来。我们报告的研究结果,从伽玛射线暴090510检测费米的LAT和GBM仪器,设置前所未有的限制光的速度对它的能量的依赖。

英文摘要:

One of the cornerstones of special relativity is the postulate that all observers measure exactly the same photon speeds independently on the photon energies. However, a hypothesized structure of spacetime may alter this conclusion at ultra-small length scales. Even a tiny energy-dependent variation in the speed of light may be revealed, when accumulated over cosmological light-travel times, by high temporal-resolution measurements of sharp features in Gamma-Ray Burst lightcurves. We report the results of a study of the emission from GRB 090510 as detected by Fermi's LAT and GBM instruments that set unprecedented limits on the dependence of the speed of light on its energy.
