COMPTON SCATTERING AND REGGE CUTS

Multiple Pomeranchuk-trajectory exchange is studied in nucleon Compton scattering as an alternative means to a wrong-signature fixed pole in order to obtain a constant total asymptotic cross section and avoid paradoxes involving the vector-meson-dominance model. It is argued that the multi-Pomeranchon branch points interfere constructively, and an estimate is made of their contributions. One finds that the inclusion of up to five-Pomeranchon branch points leads to some 40% of the total nucleon Compton cross section. The implications of these results for the Pomeranchuk trajectory are discussed. © 1969 The American Physical Society.
