Abstract
We review the methods of the computation of the scattering amplitudes in the light-front formalism. Basics of the light-front quantization, as well as helicity methods and different types of recursion relations for scattering amplitudes are reviewed. Computation of the wave-functions and fragmentation functions within the light-front theory are presented. Methods for obtaining off-shell scattering amplitudes are presented together with the new recursion relations which include the gauge invariant extensions of the off-shell amplitudes. Finally, relation between the formalism which makes use of the Wilson lines and light-front formalism is discussed.
