论文摘要
轴是Peccei-Quinn机制的自然结果,这是对强CP问题的最引人注目的解决方案。类似的轴状颗粒(ALP)也出现在标准模型的许多可能的扩展中,尤其是在字符串理论中。斧头和阿尔卑斯山都是深色物质的动机候选人,此外,它们将在太阳的核心上大量生产。在过去的十年中,相关的工作是CERN的铸造实验,CERN是最敏感的轴突启发器待办事项。国际轴心天文台(IAXO)是大规模的第四代Helioscope。作为其主要物理目标,IAXO将寻找信号与背景比率高约5个数量级的太阳轴或阿尔卑斯山脉高约5个数量级。最近,IAXO的合作提出了和中间的实验阶段Babyiaxo,该阶段是在最终系统的相关规模上测试所有IAXO子系统(磁铁,光学,探测器和阳光跟踪系统),因此可以作为IAXO的探路者,因此可以作为IAXO的探路,但与识别相关的物理学相同,并在范围内进行了相关的范围。 Babyiaxo于2019年5月获得DESY物理审查委员会的认可。在这里,我们将回顾Babyiaxo的状态和前景及其探究Axion&Alps参数空间的物理最激励地区的潜力。
Axions are a natural consequence of the Peccei-Quinn mechanism, the most compelling solution to the strong-CP problem. Similar axion-like particles (ALPs) also appear in a number of possible extensions of the Standard Model, notably in string theories. Both axions and ALPs are very well motivated candidates for Dark Matter, and in addition, they would be copiously produced at the sun's core. A relevant effort during the last decade has been the CAST experiment at CERN, the most sensitive axion helioscope to-date. The International Axion Observatory (IAXO) is a large-scale 4th generation helioscope. As its primary physics goal, IAXO will look for solar axions or ALPs with a signal to background ratio of about 5 orders of magnitude higher than CAST. Recently the IAXO collaboration has proposed and intermediate experimental stage, BabyIAXO, conceived to test all IAXO subsystems (magnet, optics, detectors and sun-tracking systems) at a relevant scale for the final system and thus serve as pathfinder for IAXO but at the same time as a fully-fledged helioscope with record and relevant physics reach in itself with potential for discovery. BabyIAXO was endorsed by the Physics Review committee of DESY last May 2019. Here we will review the status and prospects of BabyIAXO and its potential to probe the most physics motivated regions of the axion & ALPs parameter space.
