Description
We present our predictions for lifetimes, lifetime ratios and
semileptonic decay widths of single-charm (bottom) and double-charm
baryons within the Heavy Quark Expansion (HQE) framework, including all
known corrections. In contrast to earlier findings, our results
accommodate the experimentally-favoured hierarchy of the singly charmed
baryons. In the double-charm sector, we find a good agreement with the
experimental value for the lifetime of $\Xi_{cc}^{++}$, and give predictions for the remaining two unmeasured lifetime ratios. Furthermore, we find an excellent agreement between the data and the experiment for the case of single-bottom baryons.
