Abstract

The possibility of saturation of unitarity bounds for elastic hadron-hadron scattering at very high energies is discussed with respect to two limits: the MacDowell-Martin and the uniform-disk bounds. The unitarity properties of these two bounds are shown. The analysis by the generalized geometrical scaling model suggests that p¯p elastic scattering first tends to the MacDowell-Martin bound and then turns to the uniform-disk bound as the elasticity becomes larger than ∼0.4.
