Abstract
The pomeron-pomeron interaction is studied in the perturbative approac h of BFKL-Bartels. The total pomeron-pomeron cross-section is proporti onal to alpha(s)(4)s(Delta)/root t(1)t(2) where root s is the c.m. ene rgy and t(1,2) are the virtualities of the colliding pomerons. Upon ca lculating the coefficient the cross-section is found to be of the orde r 2.2 mb at root s = 6 TeV and root-T-1 similar to root-t(2) similar t o 1 GeV/c.
