Bondarenko, Sergey; Levin, Eugene; Tan, C.-I. High energy amplitude as an admixture of ‘soft’ and ‘hard’ Pomerons. (English) Zbl 1038.81523 Nucl. Phys., A 732, 73-105 (2004). Summary: In this paper an attempt is made to find an interface of the perturbative BFKL pomeron with the nonperturbative pomeron originating from non-perturbative QCD phenomena such as QCD instantons and/or scale anomaly. The main idea is that the non-perturbative pomeron involves a large scale (\(M_0\approx 2 \text{GeV}\)), which is larger than the scale from which perturbative QCD is applicable. One key result is that even for processes involving a large hard scale (such as DIS) the low \(x\) behavior is determined by an effective pomeron with an intercept having an essential nonperturbative QCD contribution.
