On the determination of ${\Theta }^{+}$ 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 ${\Theta }^{+}$, then exploiting the possibility that the ${\Theta }^{+}$ is a bound state of $K\pi N$ and in the third place I present results on a new resonant exotic baryonic state which appears as dynamically generated by the Weinberg Tomozawa $\Delta K$ interaction.
