| Research Abstract |
We have confirmed that the rise of the Hadron-Hadron total cross sections is described by the log squared of center of mass energy with the universal coefficient in all hadron systems. The size of the coefficient, 0.3mb, is naturally expected from the size of strong interaction, and this fact suggests that the unitarity limit of scattering amplitude is saturated in the new interpretation. This is a major progress since the Froissart unitarity bound was established in 1960.
