We present the dynamical origin of the P{sub 11} nucleon resonances resulting from a dynamical coupled-channels (DCC) analysis of meson production reactions off a nucleon target, which is conducted at Excited Baryon Analysis Center (EBAC) of Jefferson Lab. Two resonance poles are found in the energy region where the Roper resonance P{sub 11}(1440) was identified. Furthermore, the two resonance poles and the next higher resonance pole corresponding to P{sub 11}(1710) are found to originate from a single bare state.
