Nishiharima, Japon)In this talk I look into three different topics, addressing first the possibility that the Theta(+) is a bound state of K pi N, exploiting the results of this study to find out the contribution of two meson and one baryon components in the baryon antidecuplet 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.engbook parthttp://dx.doi.org/10.1142/9789812701855_0057http://arxiv.org/abs/nucl-th/0410071http://www.worldscientific.comopen access53Chiral DynamicsStatesFísica (Física)22 Física
