The amplitudes describing the scattering of the pseudoscalar mesons off the ground-state baryons are obtained by solving the Lippmann-Schwinger equation. We analyze in detail the effects of going beyond the t=0 approximation. Our model predicts the dynamical generation of several open-charm baryon resonances in different isospin and strangeness channels, some of which can be clearly identified with recently observed states.11 p.application/pdfeng(c) American Physical Society, 2009Partícules (Matèria)ModelsBarionsProperties of specific particlesSpecific theories and interaction modelsBaryonsinfo:eu-repo/semantics/article598749info:eu-repo/semantics/openAccess
