Truncated BFKL Series and Hadronic Collisions
We study the contribution of a truncated BFKL Pomeron series to the hadronic processes showing that a reliable description is obtained using two orders in perturbation theory. The pp(pp̄) total cross sections are described with good agreement, consistent with the unitarity bound. We also calculate the elastic scattering amplitude at non zero momentum transfer t, introducing two distinct ansätze ...
متن کاملEquivalence of the Parke-Taylor and the Fadin-Kuraev-Lipatov amplitudes in the high-energy limit.
We give a unified description of tree-level multigluon amplitudes in the high-energy limit. We represent the Parke-Taylor amplitudes and the Fadin-Kuraev-Lipatov amplitudes in terms of color configurations that are ordered in rapidity on a two-sided plot. We show that for the helicity configurations they have in common the Parke-Taylor amplitudes and the Fadin-Kuraev-Lipatov amplitudes coincide.
متن کاملA Monte Carlo Solution to the Balitsky-fadin-kuraev-lipatov Equation for Resummation in Perturbative Qcd
A simple solution to the BFKL equation is obtained as a series in the number of real gluons emitted with transverse momentum greater than some small cutoo. This solution reveals physics inside the BFKL ladder which is hidden in the standard inclusive solution, and lends itself to a straightforward Monte Carlo implementation. With this approach one can explore new useful physical observables, wh...
متن کاملTruncated BFKL Series in Electron-Proton Collisions
We study the contribution of the truncated BFKL Pomeron series to the electroproduction process showing that a reliable description is obtained taking into account two orders in perturbation theory. Using the recent F2 logarithmic slope data as a constraint to the adjustable parameters, the inclusive structure function is described in a wide range of the small x HERA kinematical region, consist...
متن کاملThe resummation approach to evolution equations
We derive the evolution equations of parton distribution functions appropriate in different kinematic regions in a unified and simple way using the resummation technique. They include the Gribov-Lipatov-Altarelli-Parisi equation for large momentum transfer Q, the Balitskii-Fadin-Kuraev-Lipatov equation for a small Bjorken variable x, and the Ciafaloni-Catani-FioraniMarchesini equation which uni...
