This document provides a comprehensive summary of the state-of-the-art, challenges, and
prospects in the experimental and theoretical study of the strong coupling $\alpha_s $. The …

Analytic continuation of the perturbative series from spacelike to timelike regions is
performed using renormalization group summed perturbation theory (RGSPT). This method …

We perform numerical analysis of double-pinched Borel–Laplace QCD sum rules for the
strangeless semihadronic τ-decay data. The D= 0 contribution to the theoretical contour …

We present a determination of the perturbative QCD (pQCD) coupling using the V+ A
channel ALEPH\(\tau\)-decay data. The determination involves the double-pinched Borel …

A bstract We present a novel method for precisely determining the QCD running coupling
from R uds measurements in electron-positron annihilation. When calculating the fixed-order …

We use improved truncated operator product expansion (OPE) for the Adler function,
involving two types of terms with dimension\(D= 6\), in the double-pinched Borel–Laplace …

The renormalization group relations for the higher-order hadronic vacuum polarization
function perturbative expansion coefficients are studied. The folded recurrent and unfolded …

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 coupling; at …
