چکیده

We provide a Mathematica package that evaluates the QCD analytic couplings (in the Euclidean domain) Aν(Q), which are analytic analogs of the powers a(Q) of the underlying perturbative QCD (pQCD) coupling a(Q) ≡ αs(Q)/π, in three analytic QCD models (anQCD): Fractional Analytic Perturbation Theory (FAPT), Two-delta analytic QCD (2δanQCD), and Massive Perturbation Theory (MPT). The analytic (holomorphic) running couplings Aν(Q), in contrast to the corresponding pQCD expressions a(Q) , reflect correctly the analytic properties of the spacelike observables D(Q) in the complex Q plane as dictated by the general principles of quantum field theory. They are thus more suited for evaluations of such physical quantities, especially at low momenta |Q| ∼ 1 GeV.

FeynHelpers: Connecting FeynCalc to FIRE and Package-X

We present a new interface called FeynHelpers that connects FeynCalc, a Mathematica package for symbolic semi-automatic evaluation of Feynman diagrams and calculations in quantum field theory (QFT) to PackageX and FIRE. The former provides a library of analytic results for scalar 1-loop integrals with up to 4 legs, while the latter is a general-purpose tool for reduction of multi-loop scalar in...

LU TP 12-40 ColorMath - A package for color summed calculations in SU(Nc)

A Mathematica package for color summed calculations in QCD (SU(Nc)) is presented. Color contractions of any color amplitude appearing in QCD may be performed, and the package uses a syntax which is very similar to how color structure is written on paper. It also supports the definition of color vectors and bases, and special functions such as scalar products are defined for such color tensors.

FAPT: A Mathematica package for calculations in QCD Fractional Analytic Perturbation Theory

We provide here all the procedures in Mathematica which are needed for the computation of the analytic images of the strong coupling constant powers in Minkowski (Āν(s;nf ) and A ν (s)) and Euclidean (Āν(Q;nf ) and A ν (Q)) domains at arbitrary energy scales (s and Q, correspondingly) for both schemes — with fixed number of active flavours nf = 3, 4, 5, 6 and the global one with taking into acc...
