International Conference on Structure of Baryons (10.2004. Palaiseau, Francia)We study the self-energy of the SU(3) antidecuplet coming from two-meson virtual clouds. Assuming that the exotic Theta(+) belongs to an antidecuplet representation with (1710) as nucleon partner, we derive effective Lagrangians that describe the decay of N(1710) into N pi pi with two pions in s- or p-wave. It is found that the self-energies for all members of the antidecuplet are attractive, and the larger strangeness particle is more bound. From two meson cloud, we obtain about 20% of the empirical mass splitting between states with different strangeness.engjournal articlehttp://dx.doi.org/10.1016/j.nuclphysa.2005.03.044http://arxiv.org/abs/hep-ph/0501116http://www.sciencedirect.comopen access53PhysicsNuclear.Física (Física)22 Física
