具有轻暗扇区和暗物质粒子的模型激发了新的对撞机搜索。本文对U(1) $_B$和U(1) $_{B-3L_{\tau}}$规范玻色子与轻暗物质耦合的亲水模型进行了综合研究。在这些模型中，新的介质粒子与夸克耦合，但抑制了与轻子的耦合，为研究得很好的暗光子模型提供了有用的衬托。我们考虑了加速器和对撞机搜索、罕见的异常诱导衰变、中微子非标准相互作用和暗物质直接探测的电流边界。尽管存在许多限制，但这些模型预测了一系列新的特征，这些特征可以在当前和不久的将来的实验中看到，包括在LHC Run 3的FASER中暗规玻色子衰变到强子最终态$\pi^+ \pi^- \pi^0$, $\pi^0 \gamma$, $K^+ K^-$和$K_S K_L$，远前中微子探测器$\nu_{\tau}$散射率的增强，以及HL-LHC时代FLArE中的热暗物质散射。因此，这些模型激发了在LHC的远前沿区域进行一系列不同的实验，这些实验可以容纳在拟议的前沿物理设施中。
Models with light dark sector and dark matter particles motivate qualitatively new collider searches. Here we carry out a comprehensive study of hadrophilic models with U(1)$_B$ and U(1)$_{B-3L_{\tau}}$ gauge bosons coupled to light dark matter. The new mediator particles in these models couple to quarks, but have suppressed couplings to leptons, providing a useful foil to the well-studied dark photon models. We consider current bounds from accelerator and collider searches, rare anomaly-induced decays, neutrino non-standard interactions, and dark matter direct detection. Despite the many existing constraints, these models predict a range of new signatures that can be seen in current and near future experiments, including dark gauge boson decays to the hadronic final states $\pi^+ \pi^- \pi^0$, $\pi^0 \gamma$, $K^+ K^-$, and $K_S K_L$ in FASER at LHC Run 3, enhancements of $\nu_{\tau}$ scattering rates in far-forward neutrino detectors, and thermal dark matter scattering in FLArE in the HL-LHC era. These models therefore motivate an array of different experiments in the far-forward region at the LHC, as could be accommodated in the proposed Forward Physics Facility.
