Abstract

Based on [Formula presented] polarized [Formula presented] events, we measure the parameter [Formula presented] to be [Formula presented] for the [Formula presented] decay. New results for the parameters [Formula presented] and [Formula presented] are also presented. Assuming that the [Formula presented]-violating phase difference is negligible, we deduce the strong phase difference between the [Formula presented]-wave and [Formula presented]-wave amplitudes of the [Formula presented] final state to be [Formula presented], reducing the uncertainty in estimating the level of [Formula presented] violation in [Formula presented]-hyperon decay.
