我们考虑未来观察附近超新星（SN）轴子发射的可能性，这可以通过超新星前警报系统、大型强子对撞机探测器（即 ATLAS 和 CMS）和 ILC 探测器（即 ILD 和 SiD）等对撞机探测器提前获知。来自SN的轴子可以通过探测器中的强磁场转换为光子，并且可以通过电磁量热计来探测光子。我们估计了由于附近的 SN 引起的信号和背景事件的数量，并表明信号的数量可能相当大。如果在 SN 时停止光束并将探测器操作切换到 SN 轴子搜索操作，则可以观察到来自附近 SN 的轴子发射。
We consider a possibility to observe the axion emission from a nearby supernova (SN) in the future, which can be known in advance by the pre-SN alert system, by collider detectors like the LHC detectors (i.e., the ATLAS and the CMS) and the ILC detectors (i.e., the ILD and SiD). The axion from the SN can be converted to the photon by the strong magnetic field in the detector and the photon can be detected by electromagnetic calorimeter. We estimate the numbers of signal and background events due to a nearby SN and show that the number of signal may be sizable. The axion emission from a nearby SN may be observed if, at the time of the SN, the beam is stopped and the detector operation is switched to the one for the SN axion search.
