Beyond the black disk limit: from shadow to antishadow scattering mode

Abstract

New mode in the hadron scattering is predicted to appear at the energies beyond $\sqrt{s}\simeq 2$ TeV: the antishadow scattering mode and the experiments at LHC and VLHC in hadronic reactions will be able to reveal it. The appearance of the antishadow scattering mode at these energies is considered on the basis of unitarity and geometrical notions of hadron interactions. Connections with the nonperturbative--QCD models are discussed.Comment: 25 pages, 2 figure
