Double strangeness pentaquarks and other exotic hadrons in the $\hat{I}{ž}_b\to \hat{I}žJ/\hat{I}¨\ddot{I}•$ decay

We study the possibility that four $\hat{I}ž$ resonances $(\hat{I}ž(1620)$, $\hat{I}ž(1690)$, $\hat{I}ž(1820)$, $\hat{I}ž(1950))$ could correspond to pentaquark states, in the form of meson-baryon bound systems…
