Gluon and dipole cascades on the light-front

Abstract

We discuss the problem of kinematic effects in the development of the gluon cascade at high energies. The modification to the original dipole kernel for the dipole evolution is proposed, which accommodates important kinematical corrections. The techniques presented in this talk utilize the perturbation theory on the light-front. Using these techniques we construct recurrence relations for the wave-functions of gluons with arbitrary number of gluon components and with exact kinematics. By combining similar techniques for the fragmentation amplitudes we rederive the MHV amplitudes.
