Abstract

We review both the counting rule and the influence of the evolution in Q² for the large x_Bj behaviour of the valance quark distribution functions. Based on a factorization procedure we present a more general perturbative treatment to compute this behaviour. A complete analysis is performed in the scalar ϕ³_[6]-theory for the parton distribution function of the ``meson'', which shows that logarithmical corrections arise from the distribution amplitude and that the reference momentum square Q₀² is fixed by x_Bj.
