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 s...

description 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 GeV^2. 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.

Our approach, based on the discrete pomeron solution, 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 GeV^2. The phases of this amplitude are sensitive to the non-perturbative gluonic dynamics and could be sensitive to the presence of Beyond-the-Standard-Model particles at very high energies.arXiv:1005.0355DESY-10-061SHEP-10-04CERN-PH-TH-2010-091DESY 10-061SHEP-10-04CERN-PH-TH-2010-091oai:cds.cern.ch:12635582010-05-04
