The BFKL-Regge phenomenology of deep inelastic scattering

Abstract
We calculate the Regge trajectories of the subleading BFKL singularities and eigenfunctions for the running BFKL pomeron in the color dipole representation. We obtain a viable BFKL-Regge expansion of the proton structure function F 2p (x,Q 2) in terms of several rightmost BFKL singularities. We find large subleading contributions to F 2p (x,Q 2) in the HERA kinematical region which explain the lack of predictive power of GLDAP extrapolations of F 2p (x,Q 2) to the region of small x. We point out the relation of our early finding of precocious BFKL asymptotic behavior to the nodal structure of subleading BFKL eigenfunctions.
