Description

We compute the mixing coefficients of the four fermion operators which appear in the non-leptonic ΔS=1, octet hamiltonian with operators of dimension five. The calculation completes the construction of the perturbative part of the weak hamiltonian, to be used in Monte Carlo simulations of lattice QCD with Wilson fermions. (orig.)
