Higgs pair production is a crucial phenomenological process in deciphering the nature of the TeV scale and the mechanism underlying electroweak symmetry breaking. At the Large Hadron Collider, this process is statistically limited. Pushing the energy frontier beyond the LHC's reach will create new opportunities to exploit the rich phenomenology at higher centre-of-mass energies and luminosities. In this work, we perform a comparative analysis of the channel at a future 100 TeV hadron collider. We focus on the and channels and employ a range of analysis techniques to estimate the sensitivity potential that can be gained by including this jet-associated Higgs pair production to the list of sensitive collider processes in such an environment. In particular, we observe that in the boosted regime exhibits a large sensitivity to the Higgs boson self-coupling and the Higgs self-coupling could be constrained at the 8% level in this channel alone.
希格斯玻色子对产生是解读TeV能标本质以及电弱对称性破缺潜在机制的一个关键唯象学过程。在大型强子对撞机中，这个过程受到统计限制。将能量前沿推进到大型强子对撞机无法企及的范围，将创造新的机会来探索更高质心能量和亮度下丰富的唯象学。在这项工作中，我们对未来100 TeV强子对撞机上的 通道进行了比较分析。我们聚焦于 和 通道，并采用一系列分析技术来估计，通过将这种与喷注相关的希格斯玻色子对产生纳入此类环境中灵敏的对撞机过程列表，所能获得的灵敏度潜力。特别地，我们观察到在增强区域， 对希格斯玻色子自耦合表现出很大的灵敏度，仅在这个通道中，希格斯玻色子自耦合就能被限制在8%的水平。
