【 摘 要 】

We present a technique that we are developing to compute the non-abelian effects to the well-known poisson distribution from QED results to obtain the QCD momentum distribution. We first introduce the MHV method used compute scattering amplitudes in gauge theory, especially N = 4 SYM, then we discuss the case of massless QCD. In second part we present why the irreducible representation of the symmetric group is the natural framework to obtain the non-abelian correction to the QED distribution.
