Density dependent relativistic hadron theory for hadron matter with inclusion of pentaquark ${\Theta }^{+}$

Xi-Guo Lee, Yuan Gao

The density dependent relativistic hadron field theory(DDRH) is extended to inclusions of pentaquark ${\Theta }^{+}$. We investigate In-medium properties of ${\Theta }^{+}$ and nucleons. As well as th…
