| dc.description | I discuss the heavy quark expansion for the inclusive widths of heavy-light hadrons, which predicts quite well the experimental ratios of B_q meson lifetimes. As for $Λ_b$, current determinations of ${\cal O}(m_b^{-3})$ contribution to $τ(Λ_b)$ do not allow to explain the small measured value of $τ(Λ_b)/τ(B_d)$. As a final topic, I discuss the implications of the measurement of the B_c lifetime. | |
