摘要：

An upgraded analysis of epsilon, X(d) and epsilon'/epsilon, using the latest determinations of the relevant experimental and theoretical parameters, is presented. Using the recent determination of the top quark mass, m(t) = (174 +/- 17) GeV, our best estimate is epsilon'/epsilon = (3.1 +/- 2.5)x 10(-4), which lies in the range given by E731. We describe our determination of epsilon'/epsilon and make a comparison with other similar studies. A detailed discussion of the matching of the full theory to the effective Hamiltonian, written in terms of lattice operators, is also given.
