摘要The spectra of baryons which include two heavy quarks and one light quark can be treated as a two- body system,where two heavy quarks constitute a bosonic diquark. We derive the effective potential between the light quark and the heavy diquark. In this work we have discussed several serious problems: (1) the operator ordering, (2) the errors caused by the non - relativistic expansion, (3) spin spin coupling and (4) the mixing between baryon states with scalar - diquark and Vector - diquark.
