Some Features of the Production of Heavy-Quark-Containing Baryons in Electron-Positron Collisions

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.
