Abstract : We describe in detail a recently published measurement of CP violation induced by B0-anti B0 oscillations, based on an integrated luminosity of 425.7 inverse fb collected by the BABAR experiment at the PEPII collider. We apply a novel technique to a sample of about 6 million B0 decays to D star l nu selected with partial reconstruction of the D star meson. The charged lepton identifies the flavor of one B meson at its decay time, the flavor of the other B is determined by kaon tagging. We determine a CP violating asymmetry ACP = (0.0006 +- 0.0017 + 0.0038 - 0.0032). This measurement is consistent and competitive with those obtained at the B factories with dilepton events.
