【 摘 要 】
We consider computational problems in the framework of nonpower Analityc Perturbation Theory and Fractional Analytic Perturbation Theory that are the generalization of the standard QCD perturbation theory. The singularity-free, finite couplings A≠(Q2);A≠(s) appear in these approaches as analytic images of the standard QCD coupling powerss (Q2) in the Euclidean and Minkowski domains, respectively. We provide a package \FAPT" based on the system Mathematica for QCD calculations of the images A≠(Q2), A≠(s) up to N3LO of renormalization group evolution. Application of these approaches to Bjorken sum rule analysis and Q2-evolution of higher twist μp-n4is considered.
