We present the dynamical origin of the P11 nucleon resonances resulting from a dynamical coupled-channels (DCC) analysis of meson production reactions off a nucleon target, which is conducted in Excited Baryon Analysis Center (EBAC) at Jefferson Lab. Two resonance poles are found in the energy region where the Roper resonance P11(1440) is supposed to be observed. Furthermore, the two resonance poles and the next higher resonance pole corresponding to P11(1710) are found to originate from a single bare state.
