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.
