dc.description.abstract	We present recent results for the prediction of the B-s(0)-(B) over bar (0)(s) lifetime difference from lattice Heavy Quark Effective Theory simulations. In order to get a next-to-leading order result we have calculated the matching between QCD and HQET and the two loop anomalous dimension in the HQET for all the DeltaB = 2 operators, in particular for the operators which enter in the width difference. me obtain far the B-s(0)-(B) over bar (0)(s) lifetime difference, Delta GammaB(s)/GammaB(s) = (5.1 +/- 1.9 +/- 1.7) x 10(-2).
