Using O"to" Re/lm and relevant forward differential cross-section data up to the highest available energies we determine the P, f, p, OJ, A2 intercepts and forward residues in nN, NN and KN scattering. We find evidence for low-lying contributions in the nN and NN non-flip amplitudes including the 0" trajectory in the nN case. We also test various phenomenological notions like exchange degeneracy (EXD) , p universality, OJ universality etc. against our parameter values. Comparison is made with other works.
By a phenomenological choice of the residue functions, a very good fit with experiment for the pion-nucleon charge exchange reaction at Fermilab energies is obtained on a simple Regge-pole model using a quadratic p trajectory and energy-independent parameters.
