EXCHANGE DEGENERACY, DUALITY AND REGGE CUTS

Duality leads to exchange degeneracy for Regge trajectories, and empirical evidence is presented that such a degenerate scheme is not satisfied. A substantial improvement results from the inclusion of Regge cut corrections. These corrections are discussed, separating for clarity the P and non-P contributions to the cut. Application is made to pairs of line reversed reactions such as K̄N and KN charge exchange, and π+p → K+Σ+ and K-p → π-Σ+. © 1969.
