我们探索了探索隐谷场景的策略，展示了限制。这样的情景导致了来自淋浴过程的大量隐藏在光中的强子。它们的衰变通常是软的和移位的，这使得它们在探索传统的大型强子对撞机搜索方面具有挑战性。我们发现，LHCb的低触发阈值和出色的轨迹和顶点重建为在介子和强子通道中搜索此类信号提供了理想的环境。我们还探索了ATLAS/CMS的潜力，并讨论了对现有搜索的修改，以使这些实验与LHCb REACH具有竞争力。我们提出的搜索可以探索到暗扇区有主导衰变的$Z^素数模型，以及孪生希格斯模型中奇异的希格斯玻色子衰变。
We explore strategies for probing Hidden Valley scenarios exhibiting confinement. Such scenarios lead to a multiplicity of light hidden hadrons from showering processes. Their decays are typically soft and displaced, making them challenging to probe with traditional LHC searches. We show the low trigger thresholds and excellent track and vertex reconstruction at LHCb provide an ideal environment to search for such signals -- in both muonic and hadronic channels. We also explore the potential of ATLAS/CMS and discuss modifications to present searches that might make these experiments competitive with the LHCb reach. Our proposed searches can probe $Z^{\prime}$ models with dominant decays to dark sectors as well as exotic Higgs boson decays in Twin Higgs models.
