Heavy flavour benchmark studies for tracking detectors at the FCC-ee

The Future Circular Collider (FCC-ee) aims to explore fundamental physics with high precision. This goal relies heavily on accurate vertexing and particle identification (PID). Precise vertexing, which determines the location of particle decays, improves signal-to-noise ratios, allows background suppression, and aids in the identification of short-lived particles. Moreover, the accurate determination of vertex locations enables the precise measurement of a particle's decay time which is an important feature in heavy flavour-physics. PID is essential for accurately measuring Higgs decays, flavour tagging, and tau-lepton physics. PID can be achieved via a measurement of a particle's time-of-flight using the tracking system. This talk discusses the possibilities and requirements on a tracking system employed at the FCC-ee within the context of heavy flavour analyses. The decay of a B-meson into a Kstar meson and two tau leptons is used as a benchmark, given its challenging decay topology and significant physics interest.
