Distributions of N=1 QCD

Abstract

We describe the N=1 supersymmetric evolution of the parton distributions with coupled gluinos and scalar quarks (Exact Supersymmetric Altarelli Parisi or ESAP). Superymmetric distributions are generated radiatively and studied as a function of both a matching scale (the match is to an intermediate AP evolution), parameterized by a scalar quark mass, and a final evolution scale. The analysis involves also a comparison with the regular AP evolution. Predictions for all the distributions are presented.
