Abstract：
The density dependent relativistic hadron field theory is extended to inclusions of pentaquark Θ⁺. We have investigated the mass modifications of nucleons and pentaquark Θ⁺ in the framework of relativistic mean field theory. We find that the effective mass, of either the nucleon or the pentaquark Θ⁺ decreases as baryon density increases. We have studied the effects of the fractions of Θ⁺ and neutron on the baryon masses. We also discussed the relations between scale density ρ_S and vector density ρ_B at different baryon fractions.
