Sensitivity of CP violation of ? decay in J/? ? ?(SIC) at STCF

The process of J/psi ->lambda(SIC) is studied using 1.0 x 10(12) J/psi Monte Carlo (MC) events at root s = 3.097 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 O(10(-4)) by measuring the asymmetric parameters of the lambda decay. Furthermore, the decay of J/psi -> lambda(SIC) also serves as a benchmark process to optimize the detector responses using the interface provided by the fast simulation software.
