In a quite general Feynman-diagram model, diffractively produced inelastic states at high energies lead to a decrease in the total cross section below and above the threshold for the process. Nondiffractive channels produce the opposite effect. Asymptotically this agrees with the eikonal approach and the Gribov Reggeon calculus. Thus one can understand the broad dip in the pp total cross section at intermediate energies and, if the triple Pomeron decouples, the resultant intersecting-storage-rings rise.
