摘要:

在这项工作中,我们研究了在未来的正负电子对撞机上的电弱和希格斯粒子的精确测量对几个典型的超对称模型的影响,包括约束最小超对称标准模型(CMSSM),非普适希格斯质量概化(NUHM 1,NUHM 2),和7维最小超对称标准模型(MSSM 7)。使用来自\textsf{GAMBIT}社区的公开数据,我们对以前的超对称性全局拟合进行后处理,以探索希格斯工厂的发现潜力,例如圆形电子正电子对撞机(CEPC),未来圆形对撞机(FCC)和国际线性对撞机(ILC)。我们表明,目前允许的参数空间,这些模型将进一步测试未来的精度测量。特别是,暗物质湮灭机制可以通过精确测量希格斯观测值来区分。

英文摘要:

In this work, we study the impact of electroweak and Higgs precision measurements at future electron-positron colliders on several typical supersymmetric models, including the Constrained Minimal Supersymmetric Standard Model (CMSSM), Non-Universal Higgs Mass generalisations (NUHM1, NUHM2), and the 7-dimensional Minimal Supersymmetric Standard Model (MSSM7). Using publicly-available data from the \textsf{GAMBIT} community, we post-process previous SUSY global fits with additional likelihoods to explore the discovery potential of Higgs factories, such as the Circular Electron Positron Collider (CEPC), the Future Circular Collider (FCC) and the International Linear Collider (ILC). We show that the currently allowed parameter space of these models will be further tested by future precision measurements. In particular, dark matter annihilation mechanisms may be distinguished by precise measurements of Higgs observables.
