Description
Forward emissions represent a unique opportunity to test perturbative QCD in new, and so far unexplored, kinematical regimes. In the semi-hard regime, where $s>>Q^2>>\Lambda_{QCD}$, pure fixed-order predictions need to be supplemented by an all-order resummation which takes into account the effect of large energy-type logarithms. The Balistky-Fadin-Kuraev-Lipatov (BFKL) approach is established as a powerful tool for performing such a resummation. The definition and the study of observables sensitive to high-energy dynamics has the double advantage of (i) allowing to clearly discern the BFKL dynamics from the fixed-order one and (ii) providing us with an auxiliary tool to extend studies in wider sectors of physics (heavy flavor, Higgs and jet physics for instance).
In this talk, I will summarize the main efforts of the Community in this direction, showing how experimental analyses at a Forward Physics Facility could significantly advance our knowledge of the high-energy regime of QCD.
