Experimental sensitivity on searching for CP violation at BES-III

The CP violation in the D system is predicted to be an unobserved level in the Standard Model. In this paper, we describe the method of searching for CP violation decay processes with the coherently produced D^0\barD^0 mesons from the \psi(3770) decay. The CP violation decay processes can be searched for at the BES-III experiment. The experimental sensitivity for searching for the CP violation can reach about a 10^-4 level with a \psi(3770) data sample of about 20 fb^-1.
