Applications of the superflavor symmetry to heavy baryon-antibaryon pair production in electron-positron collision.

The baryons containing two heavy quarks and a light quark are believed to have the diquarkquark structure and the diquark is composed of the two heavy quarks which is a spin-0 or spin-1 object. The superflavor symmetry can associate productions of such heavy baryonantibaryon pair with the heavy meson productions. The whole scenario is presented in some details in this work, and the observation prospect in future experiments is discussed.
