TL;DR
The representation of the total cross section at high energy in the next-to-leading $\ln s$ approximation is given with definition of the impact factors and explicit expression for the BFKL kernel.
Abstract
The representation of the total cross section at high energy $\sqrt s$ in the next-to-leading $\ln s$ approximation is given with definition of the impact factors and explicit expression for the BFKL kernel. The estimate of the Pomeron intercept and the next-to-leading contributions to anomalous dimensions near $j=1$ are presented.
