Inclusive decays and lifetimes of doubly charmed baryons

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, similarly as in a heavy-light meson. This leads to preasymptotic effects in semileptonic and nonleptonic decays which 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.
