通过di-Higgs加喷流产生研究Higgs自相互作用

Investigating Higgs self-interaction through di-Higgs plus jet production

Kangyu Chai, Jiang-Hao Yu, Hao Zhang

摘要:

Higgs自耦合测量对于确定Higgs势的形状和希格斯玻色子的性质是非常必要的。我们提出了在强子对撞机上实现di-Higgs+喷流末态,以提高低不变质量区Higgs自耦合的发现灵敏度。我们的模拟表明,希格斯粒子自耦合的允许区域将进一步缩小,从最新的ATLAS报告的$[-1.5,6.7]$缩小到$[0.5, 1.7]$。此外,我们发现,负的Higgs自耦合将是不利的,在未来的100 TeV对撞机的帮助下,超过$2σ$的信心水平。

英文摘要:

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.
