AI总结:

针对 GRB221009A 的高能伽马射线,本文提出中微子衰变为类轴子粒子并在银河磁场中转化为伽马射线的机制,以缓解耦合与质量约束矛盾。

摘要:

最近,LHAASO 合作组观测到来自伽马射线暴 GRB221009A 的能量高达 10 TeV 的伽马射线,这促使天文学、粒子物理和天体物理学界提出了各种可能的解释。在本文中,我们提出了一个可行的情景:中微子与 TeV 光子在伽马射线暴中共同产生,并逐渐衰变为类轴子粒子,随后这些粒子在银河系磁场中转化为伽马射线。在这种情景下,以往类轴子粒子解释与现有对相关耦合常数和质量的观测约束之间的紧张关系可以得到缓解。

英文摘要:

Recently, the LHAASO collaboration has observed the gamma rays of energies up to ten TeV from the gamma-ray burst GRB221009A, which has stimulated the community of astronomy, particle physics and astrophysics to propose various possible interpretations. In this paper, we put forward a viable scenario that neutrinos are produced together with TeV photons in the gamma-ray burst and gradually decay into the axion-like particles, which are then converted into gamma rays in the galactic magnetic fields. In such a scenario, the tension between previous axion-like particle interpretations and the existing observational constraints on the relevant coupling constant and mass can be relaxed.
