New Regge Models of Asymptotic Behavior

The properties and predictions of several new Regge models, suggested by the Serpukhov total-cross-section data, are analyzed and compared. Forward elastic $\pi N$, $\mathrm{KN}$, $\overline{K}N$, $\mathrm{NN}$, and $\overline{N}N$ scattering are considered, for Regge models incorporating strong multi-Pomeranchukon cuts, or Regge dipoles, or complex secondary trajectories. Total cross sections are fitted. Forward real parts, charge-exchange scattering, and regeneration are predicted, within subtraction constants. High-energy extrapolations are shown.
