The anatomy of $\varepsilon$'/$\varepsilon$ beyond leading logarithms with improved hadronic matrix elements
Results of a recent calculation of the effective $\Delta S$ Hamiltonian at the next-to-leading order will be presented\footnote{Work done in collaboration with A. J. Buras and M. E. Lautenbacher.. These, together with an improved treatment of hadronic matrix elements, are used to evaluate the measur...
