标题： Polarization Measurements as a Probe of Axion-Photon Coupling: a Study of GRB 221009A

摘要： 轴子类粒子（ALPs）可以在伽马射线暴（GRB）中产生，改变这些事件的电磁辐射偏振。 我们首次基于GRB 221009A的偏振测量结果，推导了轴子-光子耦合的限制，并进行了斯托克斯参数的完整计算，这是天体物理学界通常的做法。 在天文学不确定性范围内，我们对轴子-光子耦合的限制在轴子质量范围为$10^{-9}$eV 至$\lesssim m_a \lesssim 10^{-8}$eV 内具有竞争力，并进一步允许探测ALP暗物质的受关注参数空间。 显示英文摘要

摘要： Axion Like Particles (ALPs) can be produced in Gamma Ray Bursts, altering the polarization of the electromagnetic emission in these events. For the first time, we derive bounds on the axion-photon coupling from polarization measurements of GRB 221009A, performing a full calculation of the Stokes parameters, as it is typically done in the astrophysics community. Within astrophysical uncertainties, our limits on the axion-photon coupling are competitive with complementary probes in the axion mass range $10^{-9}$ eV $\lesssim m_a \lesssim 10^{-8}$ eV, further allowing to probe motivated parameter space of ALP dark matter.
