论文摘要
我们建议将FASER用作闪亮的直线壁画实验来寻找轴和轴状颗粒（ALP）。 LHC碰撞在正向方向上产生高强度和高能光子通量，该通量可以在用于限制光束的磁场中振荡成阿尔卑斯山。然后，这些阿尔卑斯山在到达Faser的磁场之前经过约100 〜M的岩石，在那里它们可以转换回光子并通过电磁量热计检测到。在未来的几年中，FASER及其后期物理设施的Faser2将能够探索其他基于实验室的实验无法访问的阿尔卑斯山参数空间区域。
We propose the use of FASER as a light-shining-through-walls experiment to search for axions and axion-like particles (ALPs). LHC collisions generate a high intensity and high energy photon flux in the forward direction which can oscillate into ALPs in the magnetic fields that are used to confine the beam. These ALPs then pass through about 100~m of rock before reaching the magnetic fields of FASER, where they can convert back into photons and be detected by an electromagnetic calorimeter. In the next years, FASER and its successor FASER2 at the Forward Physics Facility will be able to explore regions of the ALPs parameter space inaccessible by other laboratory-based experiments.
