Nature of problem:Evaluation of the values for analytic couplings in analytic QCD [the analytic analog of the power A_{υ}(Q^{2};N_{f})(α based on the dispersion relation; _{s}(Q^{2};N_{f})/π)^{υ}] represents a physical (holomorphic) function in the plane of complex squared momenta A_{υ}-q. In ^{2} ≡ Q^{2}anQCD.m we collect the formulas for three different analytic models depending on the energy scale, Q, number of flavors ^{2}N, the QCD scale Λ_{f}, and the (nonpower) index _{Nf}υ. The considered models are: Analytic Perturbation theory (APT), Two-delta analytic QCD (2δanQCD) and Massive Perturbation Theory (MPT). | ||

Solution method:anQCD uses Mathematica functions to perform numerical integration of spectral function for each analytic model, in order to obtain the corresponding analytic images via dispersion relation.A_{υ}(Q^{2}) | ||

Restrictions:It could be that for an unphysical choice of the input parameters the results are meaningless. | ||

Running time:For all operations the running time does not exceed a few seconds. |
