The $\Lambda$-parameter in 3-flavour QCD and ${\alpha }_s(m_Z)$ by the ALPHA collaboration

M. Bruno, M. Dalla Brida, P. Fritzsch +6

We present results by the ALPHA collaboration for the $\Lambda$-parameter in 3-flavour QCD and the strong coupling constant at the electroweak scale, ${\alpha }_s(m_Z)$, in terms of hadronic qua…
