论文摘要
通常会讨论未来山脉的能力，假设有特定的假设新物理学。我们考虑相反的可能性：无法访问新物理学，我们想了解不自然的标准模型是否是广阔景观的一部分。我们认为，朝这个方向迈出的主要一步将是建立希格斯潜力的不稳定性量表。这主要需要减少强耦合和顶部夸克质量的不确定性。我们表明，可以通过$ t \ bar t $阈值扫描以低$ 10^{33} \，{\ rm cm}^{ - 2} {\ rm sec}^{ - 1} $亮度在``````````````````````````''''''''''''''''''''''剂质量可以很好地测量。 Muon对撞机。
Capabilities of future colliders are usually discussed assuming specific hypothetical new physics. We consider the opposite possibility: that no new physics is accessible, and we want to learn if the unnatural Standard Model is part of a vast landscape. We argue that a main step in this direction would be establishing the possible instability scale of the Higgs potential. This primarily needs reducing the uncertainty on the strong coupling and on the top quark mass. We show that the top quark mass can be measured well enough via a $t \bar t$ threshold scan with low $10^{33}\,{\rm cm}^{-2}{\rm sec}^{-1}$ luminosity, that seems achievable at a `small' $e^+ e^-$ collider in the LEP tunnel, or at the first low-energy stage of a muon collider.
