We analyse matrix elements of DeltaB= 2 operators by combining QCD results with the ones obtained in the static limit of HQET. The matching of all the QCD operators to HQET is made at NLO order. To do that we have to include the anomalous dimension matrix up to two loops, both in QCD and HQET, and the one loop matching for all the DeltaB = 2 operators. The matrix elements of these operators are relevant for the prediction of the B - (B) over bar mixing, B-s meson width difference and supersymmetric effects in DeltaB = 2 transitions.
