Abstract

A quantitative explanation is given, using Regge poles and cuts, for unexpected features of total cross sections in the newly accessible range 25-65 GeV/c. Negative contributions from the leading vacuum cuts explain the leveling out of $σ_{T} (K^{-} N)$ and $σ_{T} (π^{-} N)$ above 25 GeV/c; they also reconcile the apparently nonconverging $K^{\pm} N$ results with a common asymptotic limit, in accord with the Pomeranchuk theorem.
