Description

Updated measurements of the lifetimes of the Lambda_b and of the B0s are obtained using the full data sample collected with the D0 detector in Run II of the Tevatron collider. For the B0s the lifetime measurement is obtained from a study of a sample of semileptonic decays, B0s--->Ds+mu+X, while in the case of the Lambda_b the fully reconstructed decay Lambda_b-->J/psi+Lambda0 is used.
