| Abstract: | In a relativistic unitary model for intermediate energy nucleon-nucleon scattering there are strong indications that the resonance-like looping behavior of the 3F3 and 1D2 amplitudes is not due to a resonance pole but to the coupling with the inelastic NNπ channel. In its most simple form the looping behavior is caused by a square root branch cut. |
