Abstract：
The contributions of the double pomeron exchange (DPE) to the production of high-energy p+ p(p) collisions are calculated using both the Ingelman-Schlein model and the Donnachie-Landshoff model of the parton distribution functions for the pomeron (P). For the D-L model, in which gluons dominate the pomeron, the cross sections at high energy increase with energy √S as ln²S or InS. Its total cross section, σ(S), is about 10²-10³ nb in the TeV energies region. For the D-L model, in which P is considered a nonperturbative gluons system and its coupling with quarks is something like isoscaler photons with C=+1, its cross-section behavior with energy is a bit complicated. In the same energy range as in the D-L model, cross sections in the D-L model are only 1-3 nb, which is smaller than that of the former by 2-3 orders of magnitude. So if we assume that the parameterizations of both models are reliable, their J/ψ production processes should themselves become a good means of testing these models.
