Abstract

The second daughter Regge trajectory and the four satellite poles which accompany it in a perturbation-theory treatment of ladder diagrams are examined in detail. Although the second daughter pole couples to equal mass two-particle states. it is very slowly moving fors>0 while the leading pole is rising rapidly towards the physical region. The daughters of the two satellite poles accompanying the first daughter trajectory are also qualitatively different from their parents. The conchision is that even, as well as odd, danghter Regge trajectories are definitely not parallel to the parent trajectory and are unlikely ever to reach the physical region.
