On the determination of $\hat{I}{˜}^{+}$ quantum numbers and other topics of exotic baryons

Abstract

In this talk I look into three different topics, addressing first a method to determine the quantum numbers of the $\hat{I}{˜}^{+}$, then exploiting the possibility that the $\hat{I}{˜}^{+}$ is a bound state of $K\ddot{I}€N$ and in the third place I present results on a new resonant exotic baryonic state which appears as dynamically generated by the Weinberg Tomozawa $\hat{I}”K$ interaction.
