Using HERA data to determine the infrared behaviour of the BFKL amplitude
Using HERA data to determine the infrared behaviour of the BFKL amplitude
We determine the infrared behaviour of the BFKL forward amplitude for gluon-gluon scattering. This amplitude leads to an excellent description of the new combined inclusive HERA data at low values of x (<0.01) and at the same time determines the unintegrated gluon density inside the proton, for squared transverse momenta of the gluon less than 100 GeV2. The phases of this amplitude are sensitive to the non-perturbative gluonic dynamics and to the presence of Beyond-the-Standard-Model particles at very high energies.

Abstract
We determine the infrared behaviour of the BFKL forward amplitude for gluon-gluon scattering. This amplitude leads to an excellent description of the new combined inclusive HERA data at low values of x (<0.01) and at the same time determines the unintegrated gluon density inside the proton, for squared transverse momenta of the gluon less than 100 GeV2. The phases of this amplitude are sensitive to the non-perturbative gluonic dynamics and to the presence of Beyond-the-Standard-Model particles at very high energies.
