An Upgraded Analysis of ϵ′/ϵ\epsilon\prime/\epsilon at the Next-to-Leading Order

An upgraded analysis of \ep, $x_d$ and \epp/\ep, using the latest determinations of the relevant experimental and theoretical parameters, is presented. Using the recent determination of the top quark mass, $m_t=(174 \pm 17)$ GeV, our best estimate is \epp/\ep= 3.1 \pm 2.5 , which lies in the range given by E731. We describe our determination of \epp/\ep 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.Comment: LaTeX, 45 pages, 6 postscript figure
