The strong coupling from ALEPH tau decays
The strong coupling from ALEPH tau decays. We use the publically available non-strange spectral function from ALEPH tau decays to critically analyze the different determinations of $\alpha_s(m^{2}_{\tau}$) that can be found in the literature and the numerical impact of their possible weaknesses. We...
