A simulation study on the measurement of D0-D0 mixing parameter y at BESⅢ
likelihood electron identification D0-D0 mixing mixing parameter y
2009/8/17
We established a method on measuring the D0-D0 mixing parameter y for BESⅢ experiment at the BEPCⅡ e+e－ collider. In this method, the doubly tagged π(3770) →D0-D0 events, with one D decays to CP-eigen...
