Experimental Particle and Astro-Particle Physics Seminar

Monday 22 Sept 2025, 14:00 → 16:00 Europe/Zurich

Stefanos Leontsinis (University of Zurich (CH))

Abstract: The Future Circular Collider (FCC) is a post-LHC project designed to provide unparalleled opportunities to advance our knowledge in high energy physics. The electron-positron stage of FCC (FCC-ee) features operation modes with an energy range from about 91 GeV to 365 GeV, serving as an electroweak, Higgs boson, and top quark factory. At the center-of-mass energies 240 and 365 GeV, the FCC-ee will produce millions of Higgs bosons via Higgs-strahlung and vector boson fusion. The clean experimental environment allows a model-independent measurements of the ZH cross-section and total Higgs width at per-mil precision, as well as a complete survey of Higgs couplings. The Z pole operation yields 6×10^12 Z bosons, enabling an ideal machine for flavor studies. This talk will review the FCC-ee physics potential and highlight selected results from the Higgs and flavor sectors.
