Prospects on Determining Electric Dipole Moments of Delta S and Delta X Hyperons at BESIII

The electric dipole moment of Delta *S (or Delta *X hyperon, d Delta *S (or d Delta *X), can be detected by analyzing the angular distribution in the decay process of . The dependence of d Delta *S (or d Delta *X) on the free parameters describing the angular distribution is studied in detail with a Monte Carlo simulation based on 109 J/ Delta *V events expected in one year data taking at BESIII. The result shows that an expected upper limit with 10-16 ~ 10-18 e cm on d Delta *S (or d Delta *X) can be achieved depending on the true values of free parameters.
