Abstract

We present new results for the renormalisation and subtraction constants for the four fermion DeltaF = 2 operators, computed non-perturbatively in the RI-MOM scheme (in the Landau gauge). From our preliminary analysis of the lattice data at beta = 6.45, for the B-0 - B-0,mixing bag-parameter we obtain B-B(RGI) = 1.46(7)(1).
