Abstract

With the High-Luminosity phase marking the final stage of the Large Hadron Collider's (LHC) operation, the focus is now shifting toward the next generation of colliders, which will prioritize lepton-based collisions in their initial stages. At the forefront of this development is CERN's proposed Future Circular Collider (FCC). The exceptional precision of measurements expected from these facilities presents a powerful means of placing tighter constraints on ultraviolet continuation models that attempt to resolve persistent issues in the Standard Model. This project seeks to assess the FCC's potential to reveal signatures of physics beyond the Standard Model. Specifically, we intend to explore how the large data sample collected at the Z-pole run of the the FCC can be used to probe the hypothesis of partial compositeness of fermions.
