A Quantum Leap Forward: Unlocking the Higgs Boson at Future Colliders — •Markus Klute — Karlsruhe Institute of Technology, Karlsruhe, Germany

The Higgs boson stands out as the most intriguing and unique particle in the Standard Model – both a manifestation of the Higgs field and a potential key to new physics. While the Large Hadron Collider has opened the door, the precision frontier –where subtle deviations from the Standard Model may reveal themselves – lies ahead. In this talk, we explore how future experiments, from the High-Luminosity LHC to proposed next-generation colliders like the FCC, aim to transform the Higgs boson from a known particle into a precision tool. By measuring its self-interaction, rare decays, and couplings with unprecedented accuracy, we may uncover clues about the nature of electroweak symmetry breaking, the hierarchy problem, and possible connections to dark matter and the early universe. These future measurements are not just incremental steps – they are a quantum leap forward in our understanding of nature.
