Abstract
The Van Hove model of Regge poles is used to study daughter trajectories of bosons in scalar meson-scalar meson scattering and
of fermions in backward pion-nucleon scattering. Both the simple model with bare propagators and a generalized model that includes propagator self-energy insertions are considered. It is found that, in the simple model, the second boson daughter and the first fermion daughter are fixed (as a function of the squared momentum transfer t or u) double poles in complex J-plane. When self-energy corrections to the propagator are included, the fixed double pole breaks up into a moving daughter trajectory and a moving aunt trajectory. It is found that away from t(u) = O, the daughter and aunt trajectories get mixed up in a complicated and model-dependent manner.
