FASER，LHC的ForwArd Search Experiment的目标是用放置在ATLAS或CMS的遥远区域的小型廉价探测器发现轻的弱相互作用粒子。在ATLAS交互点（IP）下游480 m处未使用的服务隧道中，已确定了一个有希望的位置。先前的研究发现，FASER对IP产生的新粒子具有重大的发现潜力，包括暗光子，暗希格斯玻色子和重中性轻子。在这项研究中，我们探讨了一个质的不同，“束流转储”的能力FASER，其中新的粒子产生的IP，但通过碰撞在探测器元件进一步下游。特别是，我们认为发现类轴子粒子（ALP）的标准模型，耦合通过$a \gamma \gamma$相互作用的前景。在IP产生的TeV级光子与下游130 m的TAN中性粒子吸收体碰撞，通过Primakoff过程产生ALP，然后ALP在FASER中衰减为两个光子。结果表明，FASER可以探测到质量为30 - 400 MeV，耦合为10^{-6} - 10^{-3} GeV的ALP，并讨论了ALP信号的特征和探测器的要求.
The goal of FASER, ForwArd Search ExpeRiment at the LHC, is to discover light, weakly-interacting particles with a small and inexpensive detector placed in the far-forward region of ATLAS or CMS. A promising location in an unused service tunnel 480 m downstream of the ATLAS interaction point (IP) has been identified. Previous studies have found that FASER has significant discovery potential for new particles produced at the IP, including dark photons, dark Higgs bosons, and heavy neutral leptons. In this study, we explore a qualitatively different, `beam dump' capability of FASER, in which the new particles are produced not at the IP, but through collisions in detector elements further downstream. In particular, we consider the discovery prospects for axion-like particles (ALPs) that couple to the standard model through the $a \gamma \gamma$ interaction. TeV-scale photons produced at the IP collide with the TAN neutral particle absorber 130 m downstream, producing ALPs through the Primakoff process, and the ALPs then decay to two photons in FASER. We show that FASER can discover ALPs with masses $m_a \sim 30 - 400~\text{MeV}$ and couplings $g_{a\gamma\gamma} \sim 10^{-6} - 10^{-3}~\text{GeV}^{-1}$, and we discuss the ALP signal characteristics and detector requirements.
