Issues of Reggeization in $q{q}^{\mathrm{\prime }}$ Back-Angle Scattering

The Kirschner-Lipatov result for the DLLA of high-energy $q{q}^{\mathrm{\prime }}$ backward scattering is re-derived without the use of integral equations. It is shown that part of the inequalities between the variables in the logarithmically-divergent integrals is inconsequential. The light-cone wave-function interpretation under the conditions of backward scattering is discussed. It is argued that for hadron-hadron scattering in the valence-quark model the reggeization should manifest itself at full strength starting from $s_{hh}=50Ge{V}^2$.
