Determination of αs(mZ) by the non-perturbative decoupling method

We present the details and first results of a new strategy for the determination of α 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 Λ -parameters of three-flavor QCD and pure gauge...
