论文摘要
希格斯自耦合测量对于确定希格斯玻色子潜力和性质的形状至关重要。我们建议在强子山子上使用Di-higgs加上射流最终状态，以提高低不变质量区域中希格斯自我耦合的发现敏感性。我们的模拟表明，Higgs自耦合的允许区域将从最新的Atlas报告中的$ [-1.5,6.7] $进一步缩小到[0.5，1.7] $。此外，我们发现在此信号的帮助下，在未来的100TEV撞机机上，负面的Higgs自耦合将不受$2σ$的置信度。
The Higgs self coupling measurement is quite essential for determining the shape of the Higgs potential and nature of the Higgs boson. We propose the di-Higgs plus jet final states at hadron colliders to increase the discovery sensitivity of the Higgs self coupling at the low invariant mass region. Our simulation indicates that the allowed region of the Higgs self coupling would be further narrowed from $[-1.5,6.7]$ from the most recent ATLAS report down to $[0.5, 1.7]$. Furthermore, we find negative Higgs self couplings would be disfavored beyond $2σ$ confidence level at a future 100TeV collider with the help of this signal.
