论文摘要
具有基础或复合起源的新物理模型通常与在山脉的直接搜索中与类似的烙印相关，例如，在未来的$ e+e+e- $ colliders e+e+e+colliders的衰减中，从z玻色子的衰减中生产了光伪库级。我们利用Z衰变中信号的发现与Electroweak Precision测量结果之间的相关性，作为将复合模型与基本标量量表区分开的工具。我们的结果为未来的山着人提供了一个吸引人且丰富的物理案例，并演示了Z质量的Lepton Collider如何成为Higgs领域新物理学的发现机。
New Physics models with either an elementary or composite origin are often associated with a similar imprint in a direct search at colliders, case in point being the production of a light pseudoscalar in association with a monochromatic photon from the decay of a Z boson at future $e+e-$ colliders. We exploit the correlation between the discovery of a signal in the Z decays and electroweak precision measurements as a tool to distinguish a composite model from an elementary scalar one. Our results offer an appealing and rich physics case for future colliders and demonstrate how a lepton collider at the Z mass can be a discovery machine for new physics in the Higgs sector.
