โœฆ Synopsis

The Regge-eikonal model in $" field theory is studied within the framework of Gribov's reggeon calculus. A condition is derived that indicates what sort of multireggeon exchange diagrams are important for large energies, and it is shown that the eikonal form is valid only in the weak-coupling limit, i.e., when the inner coupling constant of the reggeons goes to zero: g2 -l/in s. The breakdown of the eikonal approximation outside of this limit is shown to be an effect of inelastic intermediate states.

A previous study of the Regge-eikonal model in $" is extended to QED. First we define a reggeon amplitude that is built up by tower diagrams, and then study multiregge exchange by use of Gribov's reggeon calculus. The situation is essentially the same as in @: The eikonal approximation is the true h
