快速射电暴（FRB）是以毫秒级持续时间、高银河纬度位置和高色散测量为特征的射电暴。最近，FRB 150418的宇宙起源已经被Keane等人证实，和FRB现在是宇宙学探测器的有力竞争者。FRB信号的简单尖锐特征是探测一些基本物理定律的理想选择。在这里，我们表明，通过分析不同频率之间的延迟时间，FRB数据可以严格的上限上的光子的静止质量。对于z = 0.492的FRB 150418，可以达到m γ ≤ 5.2 × 10 − 47 g，这比电子的静止质量小1020倍，比其他天体物理来源用相同方法获得的结果小103倍。
Fast radio bursts (FRBs) are radio bursts characterized by millisecond durations, high Galactic latitude positions, and high dispersion measures. Very recently, the cosmological origin of FRB 150418 has been confirmed by Keane et al., and FRBs are now strong competitors as cosmological probes. The simple sharp feature of the FRB signal is ideal to probe some of the fundamental laws of physics. Here we show that by analyzing the delay time between different frequencies, the FRB data can place stringent upper limits on the rest mass of the photon. For FRB 150418 at z = 0.492, one can potentially reach m γ ≤ 5.2 × 10 − 47 g, which is 1020 times smaller than the rest mass of electron and is about 103 times smaller than that obtained using other astrophysical sources with the same method.
