Abstract

A composite Fermion (CF) model of quasi particle has been used to describe a diquark. Considering baryons in quark-diquark configuration,the masses of the heavy light baryons like Λc+\Lambda_{c}^{+}, Σc+\Sigma_{c}^{+}, Ξc0\Xi_{c}^{0}, Ωc0\Omega_{c}^{0} and Λb+\Lambda_{b}^{+}, Σb+\Sigma_{b}^{+}, Ξb0\Xi_{b}^{0}, Ωb\Omega_{b}^{-} have been computed using this CF model of the diquark. The results are found to be in good agreement with the corresponding experimental findings. It has been suggested that the diquark can be well described in the framework of CF model in a gauge invariant way.
