论文摘要
在大型强子对撞机（LHC）的运行3期间，目前正在获取两个遥远的实验系统：FASER + FASER $ν$和SND@LHC。它们对Atlas相互作用点（IP）产生的某些类别的超出标准模型（BSM）颗粒，MUON和中微子（IP）敏感，并沿着与加速器光束线的切线进行了数百米的传播，直至与IP相反的方向相反的方向。在HL-LHC阶段，正在准备将这些实验扩展到大型实验的建议。在讨论中也有可能建立一个能够托管以不同检测技术，运动学接受和目的为特征的远前实验的前向物理设施（FPF）。在此贡献中，我在FPF上讨论了一些BSM和SM信号和背景，主要关注与QCD相关的方面。
Two far-forward experimental systems are currently taking data during Run 3 at the Large Hadron Collider (LHC): FASER + FASER$ν$ and SND@LHC. They are sensitive to some classes of beyond-the-Standard Model (BSM) particles, muons and neutrinos produced in the ATLAS interaction point (IP) and propagating for several hundred meters along the tangent to the accelerator beamline, up to the caverns where they are respectively located, in opposite directions with respect to the IP. Proposals are being prepared to extend these experiments to bigger ones during the HL-LHC phase. Building a Forward Physics Facility (FPF) capable of hosting a number of far-forward experiments characterized by different detection techniques, kinematical acceptance and purpose, is a possibility also under discussion. In this contribution I discuss some of the BSM and SM signals and backgrounds at the FPF, mainly focusing on QCD-related aspects.
