The BFKL-Regge phenomenology of deep inelastic scattering

Nikolaev N.N., Zakharov B.G., Zoller V.R.

**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*^{2}) in terms of several rightmost BFKL singularities. We find large subleading contributions to *Fip(x, *Q^{2}) in the HERA kinematical region which explains the lack of a predictive power of GLDAP-extrapolations of *F2*_{r}(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.
