论文摘要
在本文中，我们概述了一个实验，以检测强磁场中光子转换为轴突样颗粒（ALP）。我们表明，通过调节通过Fabry-Perrot腔的偏振，以使其在调制频率下有效进攻，产生的信号与正方形成正比，而不是ALP-Photon耦合常数的第四功率。假设射击噪声是噪音的主要来源，我们估计这种方法是敏感的ALP质量的质量小于$ 10^{ - 4} ev $，并在订单上耦合到$ g_ {aγ} \ sim 1.6 \ sim 1.6 \ times 10^{ - 11}}}} \ evev} \ evev}^{gev}^{ - 1}^{ - 1}^{ - 1 a a a a a im sim 1.6 10^{ - 12} \ text {gev}^{ - 1} $，带有100 m磁铁，如Alps-iic所设想的。已经调用了具有这些特性的阿尔卑斯山，以解释乳乳外背景光（EBL）对大蓝ZAR发出的超高能量伽玛射线的明显透明度。
In this paper we outline an experiment to detect the conversion of photons to axion-like particles (ALPs) in a strong magnetic field. We show that by modulating the polarization of the light passing through a Fabry-Perot cavity so that it effectively precesses at the modulation frequency, a signal is produced that is proportional to the square as opposed to the fourth power of the ALP-photon coupling constant. Assuming shot noise to be the dominant source of noise, we estimate that this approach is sensitive ALP masses less than $10^{-4} eV$ and couplings on the order to $g_{aγ}\sim 1.6\times 10^{-11} \text{GeV}^{-1}$ with a 10m, 10 T magnet, and $g_{aγ}\sim 1.6\times 10^{-12} \text{GeV}^{-1}$ with a 100 m magnet as envisaged by ALPs-IIc. ALPs with these properties have been invoked to explain the apparent transparency of the extragalactic background light (EBL) to ultra high-energy gamma rays emitted by BLAZARs.
