A Q-DEPENDENT BFKL EQUATION

We propose a modified Balitskii-Fadin-Kuraev-Lipatov equation from the viewpoint of the resummation technique, which possesses an intrinsic dependence on momentum transfer Q, and can be analytically solved. The predictions for the gluon density xg(x) at a small Bjorken variable x are consistent with phenomenological models, and those for the proton structure function F-2(x,Q(2)) match the HERA data.
