Title: Measurement of the B{sup 0} lifetime and the B{sup 0}B{sup 0} oscillation frequency using partially reconstructed B{sup 0}{yields}D*{sup +}l{sup -}{nu}{sub l} decays

Abstract

We present a simultaneous measurement of the B{sup 0} lifetime {tau}{sub B{sup 0}} and B{sup 0}B{sup 0} oscillation frequency {delta}m{sub d}. We use a sample of about 50 000 partially reconstructed B{sup 0}{yields}D*{sup +}l{sup -}{nu}{sub l} decays identified with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring at SLAC. The flavor of the other B meson in the event is determined from the charge of another high-momentum lepton. The results are {tau}{sub B{sup 0}}=(1.504{+-}0.013(stat){sub -0.013}{sup +0.018}(syst)) ps, {delta}m{sub d}=(0.511{+-}0.007(stat){sub -0.006}{sup +0.007}(syst)) ps{sup -1}.
