Small-x Processes in Perturbative Quantum Chromodynamics

Abstract

Starting from a rewiev of DGLAP and BFKL evolution equations for small-x processes, a sistematic study is performed in order to understand the limits of both the formulations and to improve them in a unique framework, which aims to cover the whole range of applicability of perturbative QCD and which describes the transition mechanism from perturbative to non-perturbative physics in the region where unitarity contributions are expected not to be important.
