Recursion relations for the multiparton collinear limit and splitting
functions    [PDF]

Stefano Catani, Petros Draggiotis, Germán Rodrigo

We present a systematic method to evaluate the splitting functions for tree-level QCD processes where m partons approach the collinear limit. The splitting functions are computed by deriving on-shell recursion equations, which are similar to the Berends-Giele recursion relations for off-shell currents.
