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

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

Abstract We present the details and first results of a new strategy for the determination of $$\alpha _s(m_Z)$$ 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 $$\Lambda $$ Λ -param...
