A simulation study on the measurement of D0-D0bar mixing parameter y at BES-III

Bin Huang, Yang-Heng Zheng, Wei-dong Li

We established a method on measuring the $\dzdzb$ mixing parameter $y$ for BESIII experiment at the BEPCII $e^{+}{e}^{-}$ collider. In this method, the doubly tagged $ψ(3770) \to D^0 \ov…
