Descripción

This contribution compares the ILD and CLD detector concepts for FCC-ee, based on full simulation of e⁺e⁻→Z→τ⁺τ⁻ events (Pythia8, PandoraPFA). The study covers particle-level reconstruction performance (efficiency, purity, and resolution) as well as tau decay reconstruction across leptonic and hadronic channels. We further extend the comparison to a preliminary tau polarization analysis using an asymmetry-fit method, evaluating how detector-level differences propagate to the final physics observables.
