Accelerator searches for new resonances have a long-standing history of discoveries that have driven advances in our understanding of nature. Since 2010, the Large Hadron Collider (LHC) has probed previously inaccessible energy scales, enabling searches for new heavy resonances predicted by a wide range of theories beyond the Standard Model (BSM). In particular, resonance decays into fermionic final states are often seen as golden channels since they provide a clear signal—typically a peak in the invariant mass of the decay products over a smoothly falling background distribution. This review summarizes the key concepts of the experimental searches for new resonances decaying to fermions, in the context of the BSM theories that motivate them, and presents the latest results of the ATLAS and CMS experiments, focusing on the complete LHC Run 2 dataset. Future prospects at the High-Luminosity LHC and potential future colliders are also surveyed.

寻找在 LHC 中衰变为费米子的新高质量共振


加速器寻找新的共振有着悠久的发现历史，这些发现推动了我们对自然的理解进步。自 2010 年以来，大型强子对撞机 （LHC） 一直在探测以前无法接近的能尺度，从而能够搜索由标准模型 （BSM） 以外的广泛理论预测的新的重共振。特别是，共振衰变为费米子最终状态通常被视为黄金通道，因为它们提供了清晰的信号——通常是衰变产物不变质量的峰值，背景分布平稳下降。本文在激发它们 BSM 理论的背景下，总结了实验搜索衰变为费米子的新共振的关键概念，并介绍了 ATLAS 和 CMS 实验的最新结果，重点是完整的 LHC Run 2 数据集。还调查了高亮度 LHC 的未来前景和潜在的未来对撞机。
