Title: Measurement of the B-0-(B)over-bar(0) mixing parameter Delta m(d) using semileptonic B-0 decays
Abstract: We present a measurement of the B-0-(B-0) over bar mixing parameter Deltam(d) using neutral B meson pairs in a 29.1 fb(-1) data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We exclusively reconstruct one neutral B meson in the semileptonic B-0-->D*-.(+)nu decay mode and identify the flavor of the accompanying B meson from its decay products. From the distribution of the time intervals between the two flavor-tagged B meson decay points, we obtain Deltam(d)=(0.494+/-0.012+/-0.015) ps(-1), where the first error is statistical and the second error is systematic.
