The data sample used for this purpose consists of events in which one [Formula presented] meson is reconstructed in a hadronic decay mode, while the flavor of the recoiling [Formula presented] is determined with a tagging algorithm that exploits the correlation between the flavor of the heavy quark and the charges of its decay products. From the time development of the observed mixed and unmixed final states, we determine the [Formula presented] oscillation frequency [Formula presented] to be [Formula presented]. © 2002 The American Physical Society.
