Abstract
Trajectories of fermion Regge poles are calculated in a model in which a spin 1 2 particle is bound to a spin 0 core. The leading trajectory with parity (−1) j− 1 2 is much like the boson trajectory generated by similar interactions. The opposite parity trajectory satisfies the constraints of MacDowell symmetry, yet is totally distinct for s>0. The model produces a trajectory which above the elastic threshold has a small negative Im α and an increasing Re α. Such a trajectory produces poles on the physical sheet of the energy plane.
