| dc.description | We investigate medium modifications of the pentaquark $Θ^+$ in dense medium, taking into account different parities of the exotic $Θ^+$ baryon. We find that the chemical potential of the $Θ^+$ is shifted in a density-dependent way to one-loop order. We also investigated the effect of the scaled nucleon mass in dense medium on the $Θ^+$ propagator. The results turn out to depend sensitively on the scaled nucleon mass and on the parity of the $Θ^+$. | |
