Regge trajectories with square-root branch points and their Regge cuts

  • 1. Department of Physics, Rutgers University, New Brunswick, New Jersey 08903

Description

We discuss branch points in the complex angular momentum plane formed by two Regge poles on trajectories with square-root branch points at t=0. We find several new cuts which collide with the expected Mandelstam cuts at t=0. 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 α(0)=1 only if certain couplings vanish at t=0.
