摘要：
We evaluate the matrix elements of the four-quark operators which contribute to the lifetimes of B-mesons and the A(b)-baryon. We find that the spectator effects are not responsible for the discrepancy between the theoretical prediction and experimental measurement of the ratio of lifetimes tau(A(b))/tau(B).
