Abstract

We present an improved measurement of [Formula presented]-violation parameters in [Formula presented], [Formula presented], and [Formula presented] decays based on a [Formula presented] data sample collected at the [Formula presented] resonance with the Belle detector at the KEKB energy-asymmetric [Formula presented] collider. One neutral [Formula presented] meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying [Formula presented] meson is identified from its decay products. [Formula presented]-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two [Formula presented] decays. We find that the observed [Formula presented] asymmetry in the [Formula presented] decay differs from the standard model (SM) expectation by 3.5 standard deviations, while the other cases are consistent with the SM.

One neutral [Formula presented] meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying [Formula presented] meson is identified from its decay products. [Formula presented]-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two [Formula presented] decays. We find that the observed [Formula presented] asymmetry in the [Formula presented] decay differs from the standard model (SM) expectation by 3.5 standard deviations, while the other cases are consistent with the SM.
