Measurement of the [ital CP]-violation parameter Re([var epsilon][prime]/[var epsilon])

A measurement of the [ital CP]-violation parameter Re([var epsilon][prime]/[var epsilon]) has been made using the full E731 data set. We find Re([var epsilon][prime]/[var epsilon])=(7.4[plus minus]5.2[plus minus]2.9)[times]10[sup [minus]4] where the first error is statistical and the second systematic.
