论文摘要
Spin-0单线在标准模型的良好动机扩展中出现。他们的一生决定了强子和Lepton Colliders的最佳搜索策略。为了覆盖各种单线衰减长度，我们研究了希格斯衰减的界限，考虑到无形衰变，流离失所和延迟的喷气机的签名，以及未粘腐烂的拟合拟合。我们检查了通用的标量单线和放松，并获得了匹配以及它们之间的质量差异。对于每个模型，我们讨论其自然参数空间和搜索搜索。
Spin-0 singlets arise in well-motivated extensions of the Standard Model. Their lifetime determines the best search strategies at hadron and lepton colliders. To cover a large range of singlet decay lengths, we investigate bounds from Higgs decays into a pair of singlets, considering signatures of invisible decays, displaced and delayed jets, and coupling fits of untagged decays. We examine the generic scalar singlet and the relaxion, and derive a matching as well as qualitative differences between them. For each model, we discuss its natural parameter space and the searches probing it.
