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