Small-$Q^2$ extension of DGLAP-constrained Regge residues

Abstract

In a previous paper, we have shown that it was possible to use the DGLAP evolution equatio n to constrain the high-$Q^2$ ($Q^2 \ge 10$ GeV$^2$) behaviour of the residues of a high-e nergy Regge model, and we applied the developed method to the triple-pole pomeron model. W e show here that one can obtain a description of the low-$Q^2$ $\gamma^{(*)} p$ data match ing the high-$Q^2$ results at $Q^2 = 10$ GeV$^2$.
