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

We have investigated the properties of ${\mathrm{\Theta }}^{+}$ 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 ${\mathrm{\Theta }}^{+}$-nucleus and ${\mathrm{\Theta }}^{+}$ can be bind in nuclei. The depth of optical potential for ${\mathrm{\Theta }}^{+}$ in nuclear matter is estimated.
