abstract

Several new results are presented. They include
$K^0$--$\bar K^0$ mixing with Wilson Fermions, using Ward
Identities and without subtractions; $\Delta I=1/2$, $\Delta I 3/2$ and
$\varepsilon'/\varepsilon$ amplitudes with
a non-perturbatively improved action and matrix elements of SUSY
operators relevant to both $\varepsilon$ and $\varepsilon'$, including the
the magnetic ones.
Both theoretical and numerical aspects are discussed.
