N2 - The amplitude for the collision of two hadrons with the lowest order pomeron loop is calculated. Numerical calculations show that the loop contribution to the amplitude begins to dominate the single-pomeron exchange at rapidities 8–10. Full dependence of the triple-pomeron vertex on intermediate conformal weights is taken into account.
