This article reviews the Regge and multi-Regge limit of scattering amplitudes in gauge theory, with a focus on QCD and planar N=4 super-Yang-Mills theory. The large logarithms that arise in these limits are identified, and the progress towards resumming them, including next-to-next-to-leading logarithms for BFKL evolution in QCD and all-orders proposals in planar N=4 super-Yang-Mills theory, as well as the perturbative checks of those proposals, is discussed. The application of single-valued multiple polylogarithms to this important kinematical limit of particle scattering is also covered.
We review the Regge and multi-Regge limit of scattering amplitudes in gauge theory, focusing on QCD and its maximally supersymmetric cousin, planar N=4 super-Yang-Mills theory. We identify the large logarithms that aredeveloped in these limits, and the progress that has been made in resummingthem, towards next-to-next-to-leading logarithms for BFKL evolution in QCD,as well as all-orders proposals in planarN=4 super-Yang-Mills theory andthe perturbative checks of those proposals. We also cover the application ofsingle-valued multiple polylogarithms to this important kinematical limit ofparticle scattering.
