Effective mass and decay of ${\Theta }^{+}$ in nuclear matter in quark-meson coupling model

C. Y. Ryu, C. H. Hyun, J. Y. Lee +1

The in-medium mass of a $\thetaplus$, $\mtheta^*$, in cold symmetric nuclear matter is calculated by using the quark-meson coupling model. The ${\Theta }^{+}$ is treated as an MIT bag with t…
