It is pointed out that a considerable part of the colorless objects in lepton- and hadron-induced diffractive scattering processes can be considered as virtual quark-antiquark pairs in states characterized by the quantum-numbers JPC=0−+, IG=0+, where J stands for total angular momentum, I for isospin, P, C and G stand for parity, C-parity and G-parity respectively, and that such quark-antiquark pairs are created by interacting soft-gluons. Theoretical arguments and experimental evidences in support of the proposed picture are presented. |
