The BFKL-Regge Phenomenology of Deep Inelastic Scattering

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 F2p(x,Q ) in terms of several rightmost BFKL singularities. We find large subleading contributions to F2p(x,Q ) in the HERA kinematical region which explains the lack of a predictive power of GLDAP-extrapolations of F2p(x,Q ) to a domain of small x. We point out the relation of our early finding of the precocious BFKL asymptotics to the nodal structure of subleading BFKL eigenfunctions.
