QCD gluon amplitudes and wave-functions on the light-front
I will present the calculations of the gluon wave functions and scattering amplitudes in the framework of the light-front perturbation theory. It will be shown that these gluon wave functions satisfy special recurrence relations, and that the amplitudes obtained from the scattering of these wave-functions coincide with the maximally-helicity-violating-amplitudes. Finally, using the above results I will discuss an approximate scheme which incorporates important kinematic effects in the color dipole evolution kernel at small values of Bjorken x.
