Froissart Bounds for Amplitudes and Cross Sections at High Energies [PDF]
Ya. I. AzimovHigh-energy behavior of total cross sections is discussed in experiment and theory. Origin and meaning of the Froissart bounds are described and explained. Violation of the familiar log-squared bound appears to not violate unitarity (contrary to the common opinion), but correspond to rapid high-energy increase of the amplitude in nonphysical regions.View original: http://arxiv.org/abs/1204.0984
