COMPLEX ANGULAR MOMENTUM IN RELATIVISTIC S-MATRIX THEORY

Journal Article · · Physical Review (U.S.) Superseded in part by Phys. Rev. A, Phys. Rev. B: Solid State, Phys. Rev. C, and Phys. Rev. D
On the basis of unitarity and the Mandelstam representation, the analyticity and threshold behavior of the positions and residues of the poles of the scattering amplitude in angular momentum as a function of energy are discussed. The right and left cuts of the partial wave amplitude for complex l are separated, and, in a model theory in which elastic unitarity holds, the domain of analyticity in the l plane is extended to the region Rel > 1.
