Abstract
We discuss branch points in the complex angular momentum plane formed by two Regge poles on trajectories with square-root branch points at . We find several new cuts which collide with the expected Mandelstam cuts at . In the bootstrap of the Pomeranchon pole, the collection of cuts has the same effect as in the case of linear trajectories: The Pomeranchon can have only if certain couplings vanish at .
