Real Part of Amplitude and Hadron Scattering Cross Section at Superhigh Energies.

摘要

New data on measuring the ratio of the real to imaginary part of the forward scattering amplitude: rho/sub pp-bar/(sqrt s=546 GeV)=0.24+-0.04 have been considered. This result is shown to agree with the behaviour of sigma/sub tot/(s), predicted by the U-matrix model. A possibility of transition to antishadow scattering mode at superhigh energies is stated. 10 refs.; 1 fig. (Atomindex citation 19:094471)
