Hard Diffractive Production of Heavy Flavors in High Energy p+p(p) Collisions

Abstract：

The p+p(p)→p+J/ψ(γ)+X processes for energies ranging from ISR to SSC are discussed. Assuming that the structure of the Pomeron (P) is dominated by gluons with behavior of l/x at small x, the cross section for the above hard diffractive processes taking into account two main sub-diagrams and the cross section for "background" Drell-Yan processes are calculated in the lowest order of QCD. In contrast to the background cross section, which increases with InS, the diffractive hard cross section increases with (InS)², hence the latter would be far larger than the former at TeV energies. It is shown that this property is universal for other hard diffractive processes. This would provide a new method for detecting physical particles at super-high energies by choosing suitable hard diffractive processed, provided that our above assumption of the Pomeron is correct.
