The heavy-light baryon masses in the quasi-particle approach

Abstract

The masses of the heavy-light baryons like $ \Lambda^{{+}}_{{c}}$ , $ \Omega_{{c}}^{}$ , $ \Xi_{{c}}^{}$ , $ \Lambda_{{b}}^{}$ $ \Xi_{{b}}^{}$ , $ \Omega_{{b}}^{}$ and their higher states have been investigated in the framework of the mass loaded flux tube model with diquark-quark configuration for the baryons using the quasi-particle model of diquark. Regge trajectories have been analyzed. The results are found to be in reasonably good agreement with available experimental data. Regge slope and string constants have been investigated. Some interesting observations are made.
