Abstract
The time dependent mixing of B 0 d (cid:0) (cid:22) B 0 d mesons has been observed by using the correlations between the charge of D (cid:3) mesons and the weighted mean charge of particles in each hemisphere. From a reconstructed D (cid:3)(cid:6) sample corresponding to about 1.7 million hadronic Z 0 decays, the mass di(cid:11)erence between the two B 0 d mass eigenstates has been measured to be or, converting into eV=c 2 :
