摘　　要：In this study,we explore the potentials of dipole operators and four-fermion operators at low-energy lepton colliders such as Belle Ⅱ and the Super Tau Charm Facility(STCF).We utilize high-dimension operators to characterize such anomalous interactions,focusing on those that do not interfere with the Standard Model(SM) contributions.With polarized beams,the four-fermion operators and dipole moment operators can be tested with high precision.
