Abstract

We present a measurement of [Formula presented]-violating asymmetries in [Formula presented] decays based on a [Formula presented] data sample collected at the [Formula presented] resonance with the Belle detector at the KEKB asymmetric-energy [Formula presented] collider. We fully reconstruct one neutral [Formula presented] meson as a [Formula presented] [Formula presented] eigenstate and identify the flavor of the accompanying [Formula presented] meson from its decay products. From the asymmetry in the distribution of the time intervals between the two [Formula presented] meson decay points, we obtain the [Formula presented]-violating asymmetry parameters [Formula presented] and [Formula p..
