Approximate solution of the BFKL equation applicable at HERA
Abstract
We suggest a formula interpolating between the known asymptotic regimes of the BFKL equation as the approximate solution of that equation. The parameters appearing in this interpolation are fitted to the data on deep inelastic scattering in a wide range of the kinematical variables. Care is taken of the large-x domain as well, outside the HERA kinematical region. The boundaries and the interface between various dynamical regimes are also studied.
