Abstract
We show that a growth of the proton-proton total cross section with energy
can be entirely
attributed to the purely perturbative mechanism.
The infrared regularization at rather short distances
fm
allows to extend the BFKL technique
from deep inelastic to hadron-hadron scattering.
With the account of the absorption corrections our results
are in agreement with the LHC data on σtotpp.
