A Measurement of B0 Anti-B0 Oscillations Using Fully-Reconstructed Hadronic B Decays at BABAR
Flavor oscillations of neutral B mesons have been studied with e{sup +}e{sup -} annihilation data collected at center of mass energies near the {Upsilon}(4S) at the PEP-II asymmetric collider with the BABAR detector. One B{sup 0} is fully reconstructed in a hadronic decay to a flavor eigenstate. The flavor of the other B in the event is determined using an inclusive tagging algorithm which exploits the correlations between the flavor of the b quark and the charges of its decay products. By fitting the decay-time distribution of the observed mixed and unmixed final states, the oscillation frequency, {Delta}m{sub d}, is determined to be 0.516 {+-} 0.016(stat.) {+-} 0.010(syst.) ps{sup -1}.
