Since its discovery in 2012, the Higgs boson has become a powerful mirror for exploring the inner workings of the Standard Model. Each new measurement reflects a deeper aspect of its nature - from its couplings to the heaviest fermions to the faint whispers of interactions with lighter quarks, and through its dynamical behaviour at high energy, which may reveal signs of physics beyond the Standard Model. In this seminar, we will journey through what we have learned so far about the Higgs boson’s “beauty,” “charm,” and high-energy dynamics, and what remains to be uncovered - perhaps even its “strangeness.” I will discuss how current and future experiments - from the High-Luminosity LHC to the precision frontier of FCC-ee and the energy reach of FCC-hh - will transform our picture of the Higgs sector, including the long-awaited insight into its self-coupling. Together, these milestones trace the evolving reflection of the Higgs boson across experimental eras, and our deepening understanding of how it shapes the fabric of the universe.
