摘要
洛伦兹不变性破缺（LIV）是某些量子引力（QG）场景的预期结果，可能导致超相对论粒子产生能量依赖的群速度。这种能量依赖性虽然被巨大的 QG 能标 （预计在普朗克能量 GeV 量级）所抑制，但在天体物理观测中可能被探测到。在此场景中，光子穿越的宇宙学距离放大了这一效应。通过利用 MAGIC 望远镜在 2014 年 4 月 25 日至 26 日夜间记录到的来自耀变体 Mrk 421 的、能量超过 100 GeV 的显著耀发事件，我们寻找与光子能量呈线性和二次方关系的时间延迟。首次在 LIV 研究中采用分箱似然方法，我们设定了对 QG 能标的约束。对于线性场景，我们设定了亚光速情况 GeV 和超光速情况 GeV 的 下限。对于二次方场景，亚光速和超光速情况的 下限分别为 GeV 和 GeV。
