REGGEON CALCULUS DERIVED FROM EIKONAL MODEL

A reggeon calculus is derived from a hybrid perturbation-theory model using eikonal techniques. The resulting reggeon coupling functions have a simple form which enables many diagrams of interest to be evaluated explicitly. As an example, the properties of iterated Regge cuts are discussed and evaluated. Another important result is that the physical pomeron is not expected to have factorisable residues. © 1969
