摘要

我们认为，当希格斯玻色子的灵敏度在标准模型值的40%以内时，对其自耦合的测量在一个庞大而重要的理论类别中变得特别有意义。这构成了未来有影响的实验成果的目标。它来源于最近获得的结果，即当有效场论算子系数的起源来自标准模型之外的合理的违反保管的理论时，它们之间的差异可以有多极端。

A sensitivity target for an impactful Higgs boson self coupling measurement

We argue that a measurement of the Higgs boson self-coupling becomes particularly meaningful in a large and important class of theories when its sensitivity is within 40% of its Standard Model value. This constitutes a target for a future impactful experimental achievement. It is derived from recently obtained results of how extreme the differences can be between effective field theory operator coefficients when their origins are from reasonable custodial-violating theories beyond the Standard Model.
