Bjorken sum rule with hyperasymptotic precision
Cesar Ayala, Antonio Pineda
We obtain an improved determination of the normalization of the leading infrared renormalon of the Bjorken sum rule: . Estimates of higher order term…
Using improved Operator Product Expansion in Borel-Laplace Sum Rules with ALEPH decay data, and determination of pQCD coupling
Cesar Ayala, Gorazd Cvetic, Diego Teca
We use improved truncated Operator Product Expansion (OPE) for the Adler function, involving two types of terms with dimension , in the double-pinched Borel-Laplace Sum Rules…
Determination of from an hyperasymptotic approximation to the energy of a static quark-antiquark pair
Cesar Ayala, Xabier Lobregat, Antonio Pineda
We give the hyperasymptotic expansion of the energy of a static quark-antiquark pair with a precision that includes the effects of the subleading renormalon. The terminants associa…
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…
