Low-energy nucleon-nucleon potential from Regge-pole theory
The results from a potential model for the low-energy NN interaction based on Regge-pole theory are presented. The forces are due to the dominant parts of the ..pi..,eta,eta',rho,..omega..,phi,delta,epsilon,S* trajectories in the complex J plane, which are the well-known one-boson-exchange forces. Novel features are the dominant J = 0 parts of the Pomeron, f, f', and A/sub 2/ trajectories. At the Reggeon vertices we use exponential form factors, as suggested by high-energy fits. The Pomeron, f, and f' trajectories lead essentially to repulsive central Gaussian potentials. This soft-core, partially nonlocal potential model fits the NN data with chi/sup 2//data = 2.09, which is lower than any other model we know of. The NN coupling constants have reasonable values, and the contributions of the Pomeron and tensor trajectories agree with estimates from high-energy fits.
