These equations include the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) equation for a large momentum transfer Q, the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equation for a small Bjorken variable x, and the Ciafaloni-Catani-Fiorani-Marchesini (CCFM) equation, which unifies the above two equations. We propose a modified Balitsky-Fadin-Kuraev-Lipatov equation in the resummation framework, which possesses an intrinsic Q dependence, and show that its predictions for the structure function F2(x,Q2) are consistent with experimental data.
