Description
We provide an extensive study of the lifetimes of singly charmed baryons and
mesons, within the heavy quark expansion with all known corrections included.
We give our predictions for lifetimes, lifetime ratios, and semileptonic branching ratios of singly charmed baryons. Our results accommodate the experimentally-favoured hierarchy of singly charmed baryon lifetimes
τ (Ξ0c)< τ (Λ+c) < τ (Ω0c) < τ (Ξ+c) in contrast to earlier theoretical findings. Predictions for charmed meson lifetimes and semileptonic decay rates are in agreement with a recent comprehensive study and experimental results within uncertainties.
