Simple quark-duality-diagram description of n-p charge-exchange scattering. [Dual amplitude, exotic trajectory]

Journal Article · · Phys. Rev., D; (United States)
A precise one-parameter touching has been made to n-p charge-exchange data in the non-pion region vertical-bar t vertical-bar > or = 0.2 (GeV/c)/sup 2/. The dual amplitude corresponds to a simple quark duality diagram for baryon--baryon scattering. The exotic trajectory in such a description provides a large Regge scale factor for the rho..omega..fA/sub 2/ exchange, so that the experimentally observed effective trajectory is flat. (AIP)
