The pomeron-pomeron interaction in the perturbative QCD

Abstract

The pomeron-pomeron interaction is studied in the perturbative approach of BFKL-Bartels. The total pomeron-pomeron cross-section is proportional to ${\alpha }_s^4{s}^{\Delta }/\sqrt{t_1{t}_2}$ where $\sqrt{s}$ is the c.m. energy and $t_{1,2}$ are the virtualities of the colliding pomerons. Upon calculating the coefficient the cross-section is found to be of the order 2.2 mb at $\sqrt{s}=6$ TeV and $\sqrt{-t_1}\sim \sqrt{-t_2}\sim 1$ GeV/c.
