Determination of $\alpha _s(m_Z)$ by the non-perturbative decoupling method

We present the details and first results of a new strategy for the determination of $\alpha _s(m_Z)$ (ALPHA Collaboration et al. in Phys. Lett. B 807:135571, 2020). By simultaneously decoupling 3 fictitious heavy quarks we establish a relation between the $\Lambda $-parameters of three-flavor QCD an...
