Abstract
The solution to the non–forward BFKL equation in the Leading Logarithmic approximation
is expressed in terms of a sum of iterations of its kernel directly in transverse momentum
and rapidity space. Several studies of the non–forward solution are performed both at the
level of the gluon Green’s function and for a toy cross–section, including an analysis of the
diffusion properties as found in this approach. The method developed in this paper allows
for a direct inspection of the momenta in the BFKL ladder, and can be applied to solving
the non–forward BFKL equation to next–to–leading logarithmic accuracy, when the corresponding
kernel is available
