论文摘要
希格斯对生产提供了独特的手柄，用于测量希格斯自我相互作用的强度并限制希格斯电位的形状。在拟议的未来设施中，圆形100 TEV Proton-Proton对撞机将提供对该关键数量的最精确测量。在这项工作中，我们对最有希望的衰减通道进行了详细的分析，并提出了它们组合的预期灵敏度，假设集成的光度为30 AB $^{ - 1} $。根据假定的系统不确定性，我们观察到希格斯的自耦合将在68％的置信度下以3.4-7.8％的精度进行测量。
Higgs pair production provides a unique handle for measuring the strength of the Higgs self interaction and constraining the shape of the Higgs potential. Among the proposed future facilities, a circular 100 TeV proton-proton collider would provide the most precise measurement of this crucial quantity. In this work, we perform a detailed analysis of the most promising decay channels and derive the expected sensitivity of their combination, assuming an integrated luminosity of 30 ab$^{-1}$. Depending on the assumed systematic uncertainties, we observe that the Higgs self-coupling will be measured with a precision in the range 3.4 - 7.8% at 68% confidence level.
