Experimental sensitivity on searching for CP violation at BES-III

The $CP$ violation in the $D$ system is predicted to be anunobserved level in the Standard Model. In this paper, we describethe method of searching for $CP$ violation decay processes with thecoherently produced $D^0bar D^0$ mesons from the $psi(3770)$decay. The $CP$ violation decay processes can be searched for atthe BES-III experiment. The experimental sensitivity for searchingfor the $CP$ violation can reach about a $10^{-4}$ level with a$psi(3770)$ data sample of about $20$ fb$^{-1}$.
