在一些量子引力理论中，时空的泡沫结构可能导致洛伦兹不变性破坏(LIV)。伽马射线暴作为宇宙中能量最大的爆炸，为探测量子引力效应提供了有效途径。本文利用SWIFT卫星探测到的20个短伽玛暴的连续谱，给出了量子引力能量标度MQG的保守下限。由于Liv效应，不同能量的光子具有不同的速度。这将导致高能光子相对于低能光子的延迟到达。基于LiV引起的时间延迟不能长于伽玛暴的持续时间这一事实，我们给出了20个短伽玛暴的量子引力能量尺度的最保守估计。在线性校正的情况下，最严格的约束MQG>；5.05×1014GeV来自GRB 140622A。我们对MQG的限制，尽管没有以前的结果那么严格，但到目前为止是最安全和最可靠的。
In some quantum gravity theories, a foamy structure of space-time may lead to Lorentz invariance violation (LIV). As the most energetic explosions in the Universe, gamma-ray bursts (GRBs) provide an effect way to probe quantum gravity effects. In this paper, we use the continuous spectra of 20 short GRBs detected by the Swift satellite to give a conservative lower limit of quantum gravity energy scale MQG. Due to the LIV effect, photons with different energy have different velocities. This will lead to the delayed arrival of high energy photons relative to low energy ones. Based on the fact that the LIV-induced time delay cannot be longer than the duration of a GRB, we present the most conservative estimate of the quantum gravity energy scales from 20 short GRBs. The strictest constraint, MQG > 5.05 × 1014 GeV in the linearly corrected case, is from GRB 140622A. Our constraint on MQG, although not as tight as previous results, is the safest and most reliable so far.
