Several Crucial Problems in Evaluating Spectra of Baryons with Two Heavy Quarks

  • 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.

Abstract: 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.
