A simulation study on the measurement of D <sup>0</sup> -D̄ <sup>0</sup> mixing parameter <i>y</i> at BESIII
We established a method on measuring the D0-0 mixing parameter y for BESIII experiment at the BEPCII e+e+ collider. In this method, the doubly tagged ψ(3770) → D00 events, with one D decays to CP-eigenstates and the other D decays semileptonically, are used to reconstruct the signals. Since this analysis …
