Abstract

We present a measurement of the [Formula presented] mixing parameter [Formula presented] using neutral [Formula presented] meson pairs in a [Formula presented] data sample collected at the [Formula presented] resonance with the Belle detector at the KEKB asymmetric-energy [Formula presented] collider. We exclusively reconstruct one neutral [Formula presented] meson in the semileptonic [Formula presented] decay mode and identify the flavor of the accompanying [Formula presented] meson from its decay products. From the distribution of the time intervals between the two flavor-tagged [Formula presented] meson decay points, we obtain [Formula presented], where the first error is statistical and the second error is systematic.

N2 - We present a measurement of the [Formula presented] mixing parameter [Formula presented] using neutral [Formula presented] meson pairs in a [Formula presented] data sample collected at the [Formula presented] resonance with the Belle detector at the KEKB asymmetric-energy [Formula presented] collider. We exclusively reconstruct one neutral [Formula presented] meson in the semileptonic [Formula presented] decay mode and identify the flavor of the accompanying [Formula presented] meson from its decay products. From the distribution of the time intervals between the two flavor-tagged [Formula presented] meson decay points, we obtain [Formula presented], where the first error is statistical and the second error is systematic.
