Description

We present our predictions for lifetimes, lifetime ratios and semileptonic decay widths of singly-charm (bottom) mesons and baryons as well as of double-charm baryons within the Heavy Quark Expansion (HQE) framework, including all known corrections.
We find an excellent agreement between the data and the experiment for the case of singly-charmed and bottom hadrons. In particular, 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 experiment for the lifetime of Undefined control sequence \Ksi and give predictions for the remaining two unmeasured lifetime ratios.
