Abstract.

The analysis of singly-charmed hadrons has been extended to the case of doubly-charmed baryons, \(\Xi_{cc}^{++}\), \(\Xi_{cc}^{+}\) and \(\Omega_{cc}^{+}\). Doubly-charmed baryons are described as a system containing a heavy cc diquark and a light quark, as in the case of a heavy–light meson. This leads to preasymptotic effects in semileptonic and nonleptonic decays that are essentially proportional to the meson wave function. Interplay between preasymptotic effects in semileptonic and/or nonleptonic decay rates leads to very clear predictions for semileptonic branching ratios and lifetimes of doubly-charmed baryons.
