Abstract
Flavor oscillations of neutral B mesons have been studied in annihilation data collected with the BABAR detector at center-of-mass energies near the resonance. The data sample used for this purpose consists of events in which one meson is reconstructed in a hadronic decay mode, while the flavor of the recoiling 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 oscillation frequency to be .
