Natural Zeros of Regge Residues

Abstract

We discuss the method of Reggeization of invariant amplitudes with particular reference to the kinematic zeros of the residue functions at nonsense points in $J$ and at $t=0\mathrm{}$. The zeros which occur naturally at these points yield in the first case the sense-choosing solution, and in the second case a well-defined scheme, covariant evasion, for satisfying the $t=0\mathrm{}$ conditions on helicity amplitudes. Factorization is automatically satisfied in our method.
