The time dependence of Bd - Bd mixing has been measured in b b events containing one or more kaons at the SLD experiment at the Stanford Linear Accelerator Center. A simultaneous measurement of the “right sign production fraction” of kaons from B d decays has also been made. The initial state B hadron flavor was determined using the large forward-backward asymetry provided by the polarized electron beam of the SLC in combination with a jet charge technique and information from the opposite hemisphere. From a sample of 400,000 Z0 events collected by the SLD experiment at SLC from 1996 to 1998, the kaon right sign production fraction has been measured to be 0.797 ± 0.022 and the mass difference between the two Bd eigenstates has been measured to be Δ md = 0.503 ± 0.028 ± 0.020 ps−1 .
