Heavy Baryons in a Quark Model

The masses and distance configurations of the ground and excited states of heavy – charmed and bottom baryons JP =۱/۲+- ,۳/۲+-, containing a single heavy quark and a light diquark are studied within HQS limit of the HQLD sector of NRQCD framework. We find how the average distances between the heavy quark and the center of mass of the light diquark are smaller than the size of the light diquark which is in agreement with expectations from QCD sum rules and lattice QCD calculations.
