Reconciling the analytic QCD with the ITEP operator product expansion philosophy
Gorazd Cvetic, Reinhart Koegerler, Cristian Valenzuela
Analytic QCD models are those versions of QCD in which the running coupling parameter a(Q^2) has the same analytic properties as the spacelike physical quantities, i.e., no singula…
Modified Contour-Improved Perturbation Theory
Gorazd Cvetic, Marcelo Loewe, Cristian Martinez +1
The semihadronic tau decay width allows a clean extraction of the strong coupling constant at low energies. We present a modification of the standard "contour improved" method base…
Analytic QCD coupling with no power terms in UV regime
Gorazd Cvetic, Reinhart Koegerler, Cristian Valenzuela
We construct models of analytic QCD (i.e.,with the running coupling parameter free of Landau singularities) which address several problems encountered in previous analytic QCD mode…
Exponentially Modified QCD Coupling
Gorazd Cvetic, Cristian Valenzuela
We present a specific class of models for an infrared-finite analytic QCD coupling, such that at large space-like energy scales the coupling differs from the perturbative one by le…
Various versions of analytic QCD and skeleton-motivated evaluation of observables
Gorazd Cvetic, Cristian Valenzuela
We present skeleton-motivated evaluation of QCD observables. The approach can be applied in analytic versions of QCD in certain classes of renormalization schemes. We present two v…
An approach for evaluation of observables in analytic versions of QCD
Gorazd Cvetic, Cristian Valenzuela
We present two variants of an approach for evaluation of observables in analytic QCD models. The approach is motivated by the skeleton expansion in a certain class of schemes. We t…
