The new HERA data and the determination of the infrared behaviour of the BFKL amplitude

I this talk I discuss the new HERA data on the structure function F(2) obtained from a combination of HI and ZEUS results. Their high precision allows to determine the infrared behaviour of the BFKL., forward amplitude for gluon-gluon scattering. This amplitude leads to an excellent description of t...

description I this talk I discuss the new HERA data on the structure function F(2) obtained from a combination of HI and ZEUS results. Their high precision allows to determine the infrared behaviour of the BFKL., forward amplitude for gluon-gluon scattering. This amplitude leads to an excellent description of the new 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. (C) 2010 Elsevier B.V.
