TL;DR
This paper investigates how future Higgs factories' precise measurements can constrain the MSSM parameter space, especially the stop sector, by performing multi-variable fits to Higgs signals and mass predictions.
Contribution
It provides a detailed analysis of the MSSM parameter sensitivity at future Higgs factories, focusing on the stop sector and Higgs mass predictions, which is a novel comprehensive approach.
Findings
Sensitivity to mA, tan beta, and stop mass parameters.
Higgs mass predictions significantly constrain MSSM parameters.
Different Higgs factories show varying sensitivities.
Abstract
In this work, we study the implication of Higgs precision measurements at future Higgs factories on the MSSM parameter space, focusing on the dominant stop sector contributions. We perform a multi-variable fit to both the signal strength for various Higgs decay channels at Higgs factories and the Higgs mass. The chi-square fit results show sensitivity to mA, tan beta, stop mass parameter mSUSY as well as the stop left-right mixing parameter Xt. We also study the impact of the Higgs mass prediction on the MSSM and compare the sensitivities of different Higgs factories.
