Abstract: The study of the charge conjugation and parity (CP) violation of hyperon is the precision frontier for probing possible new CP violation sources beyond the standard model (SM). With the large number of quantum entangled hyperon-antihyperon pairs to be produced at Super Tau-Charm Facility (STCF), the CP asymmetry of hyperon is expected to be tested with a statistical sensitivity of 10⁻⁴ or even better. To cope with the statistical precision, the systematic effects from various aspects are critical and need to be studied in detail. In this paper, the sensitivity effects on the CP violation parameters associated with the detector resolution, including those of the position and momentum, are studied and discussed in detail. The results provide valuable guidance for the design of STCF detector.
