Abstract

We have analyzed [Formula Presented] and [Formula Presented] events produced in the inclusive reaction [Formula Presented] and have measured some properties of the [Formula Presented] and [Formula Presented] hyperons via the decay [Formula Presented] The measured [Formula Presented] lifetime was [Formula Presented] and the measured decay parameter was [Formula Presented] The corresponding values for the [Formula Presented] were [Formula Presented] and [Formula Presented] In addition, the measurement of the normalized mass difference between the [Formula Presented] and [Formula Presented] yielded [Formula Presented] The measurements were all in good agreement with CPT invariance.
