在100 TeV p-p对撞机上通过Higgs对产生测量Higgs自耦合

Measuring the Higgs self-coupling via Higgs-pair production at a 100 TeV p-p collider

Michelangelo Mangano, Giacomo Ortona, Michele Selvaggi

摘要:

希格斯对的产生为测量希格斯自相互作用的强度和限制希格斯势的形状提供了一个独特的手柄。在拟议的未来设施中,一个圆形的100 TeV质子-质子对撞机将提供对这一关键量的最精确测量。在这项工作中,我们进行了详细的分析,最有前途的衰变通道,并得出预期的灵敏度,它们的组合,假设一个积分亮度为30 ab $^{-1}$。根据假设的系统不确定性,我们观察到,希格斯自耦合将测量精度在3.4 - 7.8%的范围内,在68%的置信水平。

英文摘要:

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.
