The Heavy Neutral Lepton (HNL) model extends the Standard Model by introducing right-handedneutrinos, which provide a plausible explanation for neutrino masses via the seesaw mechanism. Thispaper investigates the detection prospects for HNLs at the Future Circular Collider electron-positron(FCC-ee) experiment. The study focuses on comparing Fast and Full Simulations, evaluating trackingperformance and reconstruction accuracy for long-lived HNL decays.
