${\Theta }^{+}$ hypernuclei in relativistic mean field model

Abstract

We have investigated the properties of ${\Theta }^{+}$ in nuclei within the framework of relativistic mean field. The coupling constants are educed with quark meson coupling model. There is strong attractive interaction for ${\Theta }^{+}$-nucleus and ${\Theta }^{+}$ can be bind in nuclei. The depth of optical potential for ${\Theta }^{+}$ in nuclear matter is estimated.
