Superasymptotic and hyperasymptotic approximation to the operator product expansion
Cesar Ayala, Xabier Lobregat, Antonio Pineda
Given an observable and its operator product expansion (OPE), we present expressions that carefully disentangle truncated sums of the perturbative series in powers of from the…
anQCD: a Mathematica package for calculations in general analytic QCD models
Cesar Ayala, Gorazd Cvetic
We provide a Mathematica package that evaluates the QCD analytic couplings (in the Euclidean domain) , which are analytic analogs of the powers of th…
The bottom quark mass from the system at NNNLO
Cesar Ayala, Gorazd Cvetic, Antonio Pineda
We obtain an improved determination of the normalization constant of the first infrared renormalon of the pole mass (and the singlet static potential). For it reads $N_m=0.…
Extended analytic QCD model with perturbative QCD behavior at high momenta
César Ayala, Carlos Contreras, Gorazd Cvetič
In contrast to perturbative QCD, the analytic QCD models have running coupling whose analytic properties correctly mirror those of spacelike observables. The discontinuity (spectra…
