论文摘要
隐藏的部门可能会引起LHC的各种事件。众所周知，当隐藏的扇区在高能以弱耦合时会产生少量的喷气机，而准确的柔软无聚集的能量模式（sueps）是在高能以高能耦合（大't Hooft耦合）时。中级政权是模糊的，可能会引起避开现有搜索策略的信号。虽然中间耦合方案是不可计算的，但可以采用一种现象学方法，在这种现象学方法中，人们创建了球形和码头之间的信号。我们提出了一种在额外的维度中使用简化模型生成此类事件的策略。事件看起来球形的程度与运动阈值附近产生的衰减数有关。我们提供了如何通过模型参数确定的分析理解。为了量化该模型产生的事件形状，我们使用了最近提出的可观察到的 - 事件各向同性---这是比起早期的事件形状可观察结果更好的球形制度探针。
Hidden sectors could give rise to a wide variety of events at the LHC. Confining hidden sectors are known to engender events with a small number of jets when they are weakly-coupled at high energies, and quasi-spherical soft unclustered energy patterns (SUEPs) when they are very strongly-coupled (large 't Hooft coupling) at high energies. The intermediate regime is murky, and could give rise to signals hiding from existing search strategies. While the intermediate coupling regime is not calculable, it is possible to pursue a phenomenological approach in which one creates signals that are intermediate between spherical and jetty. We propose a strategy for generating events of this type using simplified models in extra dimensions. The degree to which the event looks spherical is related to the number of decays produced near kinematic threshold. We provide an analytic understanding of how this is determined by parameters of the model. To quantify the shape of events produced with this model, we use a recently proposed observable---event isotropy---which is a better probe of the spherical regime than earlier event shape observables.
