Extraction of $α_{s}$ using Borel-Laplace sum rules for tau decay data

César Ayala, Gorazd Cvetič, Diego Teca

Double-pinched Borel-Laplace sum rules are applied to ALEPH $τ$ -decay data. For the leading-twist ( $D = 0$ ) Adler function a renormalon-motivated extension is used, and the 5-loop co…

Determination of perturbative QCD coupling from ALEPH $τ$ decay data using pinched Borel-Laplace and Finite Energy Sum Rules

Cesar Ayala, Gorazd Cvetic, Diego Teca

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