Abstract

We established a method on measuring the D°-D° mixing parameter y for BESHI experiment at the BEPCII e⁺e collider. In this method, the doubly tagged ↓(3770) -> D°D° events, with one D decays to CP-eigenstates and the other D decays semileptonically, are used to reconstruct the signals. Since this analysis requires good e/π separation, a likelihood approach, which combines the dE/dx, time of flight and the electromagnetic shower detectors information, is used for particle identification. We estimate the sensitivity of the measurement of y to be 0.007 based on a 20 fb ^-1 fully simulated MC sample.
