A fresh look at the B semileptonic branching ratio and beauty lifetimes
We discuss two problems in the theory of heavy-quark decays: an understanding of the semileptonic branching ratio of B mesons, and of the lifetime ratio \tau(\Lambda_b)/\tau(B^0). We also present a model-independent study of spectator contributions to the lifetimes of beauty hadrons.
