Description

I will present a strong coupling constant extraction at next-to-leading order QCD accuracy using ATLAS Z+2,3,4 jets data. This is the first extraction using processes with a dependency on high powers of the coupling constant. The values of the strong coupling constant at the Z mass obtained are compatible with the world average and with uncertainties commensurate with other next-to-leading order extractions at hadron colliders.
