论文摘要
我们研究了未来的强子和Lepton Colliders强烈相互互动的顶级夸克的现象学，这表明特征性的四端接触操作员带来了最重要的影响。我们证明了100个TEV质子 - 普罗顿对撞机的非凡潜力，可以直接测试四顶生产中的这种非标准相互作用，这一过程我们在同一签名的Dilepton和Trilepton通道中进行了彻底分析，并在完全悬岩通道中进行探索。此外，表明高能电子峰壳（例如CLIC或ILC）表现出对四顶操作员的间接而又显着的敏感性，因为这些群体是通过重新分配组Evolution构成的，这是Top-Quark对生产中领先的新物理变形。我们研究了结果对复合希格斯模型的参数空间的影响，并具有强耦合（右手）的顶级夸克，发现四顶探针在未来能量前沿的综合量表上提供了最佳的灵敏度。此外，我们研究了Multilepton Plus Jets最终状态中的轻度但持续的LHC过量，表明它们可以在这种新物理场景的有效领域理论中持续描述。
We study the phenomenology of a strongly-interacting top quark at future hadron and lepton colliders, showing that the characteristic four-top contact operators give rise to the most significant effects. We demonstrate the extraordinary potential of a 100 TeV proton-proton collider to directly test such non-standard interactions in four-top production, a process that we thoroughly analyze in the same-sign dilepton and trilepton channels, and explore in the fully hadronic channel. Furthermore, high-energy electron-positron colliders, such as CLIC or the ILC, are shown to exhibit an indirect yet remarkable sensitivity to four-top operators, since these constitute, via renormalization group evolution, the leading new-physics deformations in top-quark pair production. We investigate the impact of our results on the parameter space of composite Higgs models with a strongly-coupled (right-handed) top quark, finding that four-top probes provide the best sensitivity on the compositeness scale at the future energy frontier. In addition, we investigate mild yet persisting LHC excesses in multilepton plus jets final states, showing that they can be consistently described in the effective field theory of such a new-physics scenario.
