Abstract

Recent measurements of lifetimes of some b-flavored hadrons are presented and interpreted in the context of theoretical models, especially the Heavy Quark Expansion. Decay widths and decay width differences in the B_s⁰-B_s⁰ system are discussed from studies of decays into the final states J/ψK⁺K^-, J/ψπ⁺π^-, D_s⁺D_s^-, K⁺K^-, and D_s^±π^∓. Lifetime measurements of the baryons Λ_b⁰, Ξ_b^-, Ξ_b⁰, and Ω_b^- are also shown.
