Supersymmetric scaling violations. I: Solving the supersymmetric DGLAP evolution. (English) Zbl 0990.81139
Summary: We analyze the renormalization group equations of supersymmetric QCD with \(N=1\) for the evolution of parton distributions. For this purpose we developed a simple recursive algorithm in \(x\) space to include both regular regions and supersymmetric regions in the evolution in the step approximation. Supersymmetric distributions are generated within a radiative model, with vanishing initial conditions for the superpartners. Here we focus on a scenario with broken susy, characterized by a lighter gluino coupled to the standard evolution and a decoupled scalar quark. Predictions for the all the distributions are presented.
