Abstract
We describe in detail a previously published measurement of violation in - oscillations, based on an integrated luminosity of collected by the BABAR experiment at the PEPII collider. We apply a novel technique to a sample of about 6 million decays selected with partial reconstruction of the meson. The charged lepton identifies the flavor of one meson at its decay time, the flavor of the other is determined by kaon tagging. We determine a violating asymmetry corresponding to . This measurement is consistent and competitive with those obtained at the factories with dilepton events.
