论文摘要
我们研究了基于实验室的替代搜索轴和轴突样颗粒与光子的偶联的前景。在这里，两个激光束的碰撞会共振产生轴，并在磁重新转换后检测到信号光子，如在闪亮的直通墙（LSW）实验中。传统的搜索，例如LSW或异常的双折射测量，对可以实现实质连贯性的轴质量最敏感。这通常远低于光能。我们发现，使用当前可用的高功率激光器设施，我们的方法可以在$ 0.5-6 $ eV之间胜过传统LSW，这是由光学激光频率和碰撞角度设置的。可以通过从激光子结构上散射连贯的散射，探测轴 - 光子耦合至$ g_ {aγγ} \ sim 10^{ - 8} {\ text {gev}^{ - 1}} $，可与现有的铸件范围相提并论。假设每个角步长一天的测量值，则可以达到QCD轴突。
We investigate the prospect of an alternative laboratory-based search for the coupling of axions and axion-like particles to photons. Here, the collision of two laser beams resonantly produces axions, and a signal photon is detected after magnetic reconversion, as in light-shining-through-walls (LSW) experiments. Conventional searches, such as LSW or anomalous birefrigence measurements, are most sensitive to axion masses for which substantial coherence can be achieved; this is usually well below optical energies. We find that using currently available high-power laser facilities, the bounds that can be achieved by our approach outperform traditional LSW at axion masses between $0.5-6$ eV, set by the optical laser frequencies and collision angle. These bounds can be further improved through coherent scattering off laser substructures, probing axion-photon couplings down to $g_{aγγ}\sim 10^{-8} {\text{GeV}^{-1}}$, comparable with existing CAST bounds. Assuming a day long measurement per angular step, the QCD axion band can be reached.
