摘要
类轴子粒子（ALPs）是在标准模型之外的多种理论中涌现出的赝南部-戈德斯通玻色子。这些粒子可以在外部磁场中与高能光子相互作用，从而影响观测到的伽马射线谱。本研究分析了 MAGIC 望远镜收集的 41.3 小时英仙座星系团观测数据。我们聚焦于星系团中心的射电星系 NGC 1275 的能谱。通过对该目标周围的磁场进行建模，我们搜寻了 ALP 存在的谱迹象。尽管未发现 ALP 特征的统计证据，我们仍能排除亚微电子伏特范围内的 ALP 模型。我们的分析通过计算所有考虑模型在参数空间中的完整似然和统计覆盖，改进了先前的工作。因此，我们在 ALP 质量约为 50 neV 处获得了迄今为止最严格的限制，耦合常数下限达到 GeV。
