Abstract：
The hard double diffractive production processes p+p(p)→p+p(p)+J/ψ(γ)+X at high energies are discussed. Under the assumption that gluon distribution with a behavior of l/x at small x in Pomeron is dominant, the dependence of cross section on energy √s is calculated. Comparisons with single diffractive hard process and corresponding non-diffractive Drell-Yang process are made. The present results show that the hard double diffractive processes are similar to single diffractive process, i.e., at extra-high energies the cross section basically increases in a manner of (In S)². The importance of this discovery for experiments is also pointed out.
