Abstract
In the framework of the dipole picture of the BFKL
pomeron we discuss two possibilities of calculating the total
cross section of the virtual photons.
It is shown that the dipole model reproduces the results obtained earlier
from kT-factorization up to the selection of the scale determining
the length of the QCD cascade. The choice of scale turns out to be important
for the numerical outcome of the calculations.
