摘要:

我们已经搜索了14.4 keV的太阳轴子或更一般的类轴子粒子(ALP),这可能是在M1核跃迁的57 Fe,通过使用轴子到光子的转换在欧洲核子研究中心的轴子太阳望远镜(CAST)与真空磁铁孔(阶段I)。当磁体指向太阳时,单能X射线不存在过剩,我们对耦合到两个光子和一个核子g_{aγ}的赝标粒子的耦合常数设置了与模型无关的约束|-1.19 g_{aN} ^{0}+ g_{aN} ^{3}|对于m_{a} <0.03 eV,在95%置信水平下,<1.36 \times 10^{-16} GeV^{-1}。

英文摘要:

We have searched for 14.4 keV solar axions or more general axion-like particles (ALPs), that may be emitted in the M1 nuclear transition of 57Fe, by using the axion-to-photon conversion in the CERN Axion Solar Telescope (CAST) with evacuated magnet bores (Phase I). From the absence of excess of the monoenergetic X-rays when the magnet was pointing to the Sun, we set model-independent constraints on the coupling constants of pseudoscalar particles that couple to two photons and to a nucleon g_{aγ} |-1.19 g_{aN}^{0}+g_{aN}^{3}|<1.36\times 10^{-16} GeV^{-1} for m_{a}<0.03 eV at the 95% confidence level.
