Diquarks are described in the framework of composite fermion (CF) model of quasi particle. The masses of the light [Λ0, Σ-, Ξ-, Ω-], heavy [Λ+c, Λ0b, Σ+c, Σ0b, Ξ0c, Ξ0b, Ω0c, Ω-b], doubly heavy [Ξ++cc ,Ξ+cc, Ξ0cb, Ξ+cb ,Ξ0bb, Ξ-bb, Ω+cc, Ω0cb, Ω-bb ] and triply heavy [Ωccc, Ωccb, Ωcbb, Ωbbb] baryons have been studied for JP = (1/ 2)+ and (3/2)+ states, considering the diquark-quark configuration for the baryons. The results are found to be in good agreement with available experimental data and other theoretical works.
