英文摘要We extract the matrix elements of four-quark operators O-L,O-S relevant to the B-s and (B) over bar (s) life time difference from QCD sum rules. We find that the vacuum saturation approximation works reasonably well, i.e., within 10%. We discuss the implications of our results and compare them with a recent lattice QCD determination.
