报告摘要

　　The precise study of Higgs boson production is essential both for testing the Standard Model and for probing the Higgs self-coupling through di-Higgs processes. Constraints on the Higgs self-coupling can be obtained through direct searches for double-Higgs production as well as indirectly via precision measurements of single-Higgs processes, where electroweak corrections provide sensitivity to this parameter. The combination of these measurements enables a more comprehensive understanding of the Higgs sector and improves constraints on fundamental couplings that are directly linked to the structure of the Higgs potential and the stability of the electroweak vacuum.

　　Furthermore, as the LHC moves toward higher energies and luminosities, major detector upgrades will be crucial to fully exploit the physics potential of future datasets. In this context, the ATLAS Inner Tracker (ITk) and the High Granularity Timing Detector (HGTD) will play key roles in enhancing experimental sensitivity, particularly in the challenging environment of the High-Luminosity LHC era.
