CERN的CAST实验的轴子物理结果

Results on axion physics from the CAST Experiment at CERN

Christos Eleftheriadis

摘要:

轴子预计将通过Primakoff过程在太阳中产生。在实验室中,在强磁场的影响下,通过逆过程可以检测到它们,从而产生能量在几keV范围内的X射线。这样的一个轴子探测器是欧洲核子研究中心的轴子太阳望远镜(CAST),从2003年开始收集数据。结果已经发表,推动轴子光子耦合g $_{aγ}$低于10 $^{-10}$ GeV $^{-1}$限制在95% CL,轴子质量小于0.02 eV。这个极限比以前的实验极限低了近一个数量级,并且第一次超过了基于能量损失概念的天体物理学参数所设定的极限。该实验目前正在探索0.02 eV $< m_a <$ 1.1 eV范围内的轴子质量。在下一次运行中,目前正在准备中,探索的轴子质量将扩展到1.1 eV的极限,第一次用轴子日光镜方法测试理论轴子模型的区域。

英文摘要:

Axions are expected to be produced in the sun via the Primakoff process. They may be detected through the inverse process in the laboratory, under the influence of a strong magnetic field, giving rise to X-rays of energies in the range of a few keV. Such an Axion detector is the CERN Axion Solar Telescope (CAST), collecting data since 2003. Results have been published, pushing the axion-photon coupling g$_{aγ}$ below the 10$^{-10}$ GeV$^{-1}$ limit at 95% CL, for axion masses less than 0.02 eV. This limit is nearly an order of magnitude lower than previous experimental limits and surpassed for the first time limits set from astrophysical arguments based on the energy-loss concept. The experiment is currently exploring axion masses in the range of 0.02 eV $< m_a <$ 1.1 eV. In the next run, currently under preparation, the axion mass explored will be extended up to the limit of 1.1 eV, testing for the first time the region of theoretical axion models with the axion helioscope method.
