We present a formalism to evaluate QCD diagrams with a single virtual gluon using a running coupling constant at the vertices. This method, which corresponds to an all-order resummation of certain terms in a perturbative series, provides a description of the momentum flow through the gluon propagator. It can be viewed as a generalization of the scale-setting prescription of Brodsky, Lepage and Mackenzie to all orders in perturbation theory. In particular, the approach can be used to investigate… Expand
Applying generalized Padé approximants in analytic QCD models
A method of resummation of truncated perturbation series, related to diagonal Pad\'e approximants but giving results independent of the renormalization scale, was developed more than ten years ago byExpand
Evaluations of low-energy physical quantities in QCD with IR freezing of the coupling
The MS-like schemes in QCD have in general the running coupling which contains Landau singularities, i.e., singularities outside the timelike semi-axis, at low squared momenta. As a consequence,Expand
The physics of hadrons
Abstract The calculation of perturbative corrections to the moments of the hadronic mass distribution in τ decays is reconsidered. The exact order-α s 3 results and the resummation procedure of LeExpand
Higher-order QCD perturbation theory in different schemes: from FOPT to CIPT to FAPT
Results on the resummation of non-power-series expansions of the Adler function of a scalar, DS, and a vector, DV, correlator are presented within fractional analytic perturbation theory (FAPT). TheExpand
αs from τ decays: contour-improved versus fixed-order summation in a new QCD perturbation expansion
We consider the determination of αs from τ hadronic decays, by investigating the contour-improved (CI) and the fixed-order (FO) renormalization-group summations in the frame of a new perturbationExpand
The QCD running coupling
Abstract We review the present theoretical and empirical knowledge for α s , the fundamental coupling underlying the interactions of quarks and gluons in Quantum Chromodynamics (QCD). The dependenceExpand
B → D* zero-recoil formfactor and the heavy quark expansion in QCD: a systematic study
A bstractWe present a QCD analysis of heavy quark mesons focussing on the B → D* formfactor at zero recoil, FD* (1). An advanced treatment of the perturbative corrections in the Wilsonian approach isExpand
Lattice-motivated QCD coupling and hadronic contribution to muon g − 2
We present an updated version of a QCD coupling which fulfills various physically motivated conditions: at high momenta it practically coincides with the perturbative QCD (pQCD) coupling; atExpand
Perturbative QCD in acceptable schemes with holomorphic coupling
Perturbative QCD in mass independent schemes leads in general to running coupling a(Q2) which is nonanalytic (nonholomorphic) in the regime of low spacelike momenta |Q2|≲1 GeV2. Such (Landau)Expand
Resurgence of the QCD Adler function
Perturbation theory is still the best available tool to deal with Quantum Chromodynamics (QCD) at high energies, where the theory is weakly coupled due to asymptotic freedom [1, 2]. However, at lowExpand
