论文摘要
如果Electroweak量表保持稳定，发现新物理学需要什么光度？在这项工作中，我们研究了这个问题，以真实的单线标量为例，该标量已将其耦合到Higgs领域已在可重新分布的水平上。观察到Electroweak量表保持稳定，如果两个标量夫妇以可见的方式表明，我们表明HL-LHC预计会在3/ab左右提供集成的光度，可以发现重达800 GEV的标量。另一方面，FCC-HH可以以100/ab的发光度发现标量为2.3 TEV。因此，因此，不破坏电动量表的新物理学只能在高光度下访问，并且不可能被当前的LHC结果排除。
What is the luminosity needed for discovering new physics if the electroweak scale is to remain stable? In this work we study this question, with the example of a real singlet scalar which couples to the Higgs field already at the renormalizable level. Observing that the electroweak scale remains stable if the two scalars couple in a seesawic fashion, we show that the HL-LHC, expected to deliver an integrated luminosity around 3/ab, can discover scalars weighing up to 800 GeV. The FCC-hh, on the other hand, can discover scalars as heavy as 2.3 TeV at 100/ab luminosity. It thus follows that the new physics that does not destabilize the electroweak scale can be accessed only at high luminosities, and is not possible exclude by the current LHC results.
