  The production of various heavy-quark-containing baryons in electron-positron
annihilation is considered. On the basis of exact formulas that we obtained
previously within full perturbation theory, new numerical calculations of the
respective cross sections are performed, and simple approximate expressions are
then constructed for the results of these calculations. The dependence of the
total cross sections on the masses of constituent quarks is discussed. The
application of the Peterson fragmentation function and a Reggeon-type
fragmentation function to describing differential cross sections is analyzed.
