Abstract

We report a measurement of the [Formula presented] mixing parameter [Formula presented] using [Formula presented] of data collected near the [Formula presented] resonance with the Belle detector at KEKB. [Formula presented] is measured from the lifetime difference of [Formula presented] mesons decaying into the [Formula presented] state and the [Formula presented]-even eigenstate [Formula presented]. We find [Formula presented], where the first error is statistical and the second is systematic, corresponding to a [Formula presented] confidence interval [Formula presented].
