Sensitivity of CP violation of Λ decay in J/ψ → ΛΛ̄ at STCF

The process of [Formula: see text] is studied using [Formula: see text] [Formula: see text] Monte Carlo (MC) events at [Formula: see text] GeV with a fast simulation software at future Super Tau Charm Facility (STCF). The statistical sensitivity for CP violation is determined to be the order of [Formula: see text] by measuring the asymmetric parameters of the [Formula: see text] decay. Furthermore, the decay of [Formula: see text] also serves as a benchmark process to optimize the detector responses using the interface provided by the fast simulation software.
