Measurement of the<i>CP</i>-violation parameter Re(ɛ’/ɛ)

A measurement of the CP-violation parameter Re(\ensuremath{\varepsilon}'/\ensuremath{\varepsilon}) has been made using the full E731 data set. We find Re(\ensuremath{\varepsilon}'/\ensuremath{\varepsilon})=(7.4\ifmmode\pm\else\textpm\fi{}5.2\ifmmode\pm\else\textpm\fi{}2.9)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}4}$ where the first error is statistical and the second systematic.
