We apply the SchrGdinger Functional (SF) f ormalism to determine the renormalisation group running of fourfermion operators which appear in the effective weak Hamiltonian of the Standard Model. Our calculations are done using Wilson fermions and the parity-odd components of the operators. Preliminar
We present new results for the renormalisation and subtraction constants for the four fermion AF = 2 operators, computed non-perturbatively in the RI-MOM scheme (in the Landau gauge). From our preliminary analysis of the lattice data at p = 6.45, for the B" -B" mixing bag-parameter we obtain BEG' =
