The strong coupling from ALEPH tau decays

We analyze some of the different determinations of αs(mτ2) that can be found in the literature and the numerical impact of their possible weaknesses with the publicly available non-strange spectral function from ALEPH tau decays. We also introduce some novel approaches. We find very stable results and uncertainties dominated by the perturbative part. Our final value is αs(mτ2)=0.328±0.013.
