Abstract

The two highest precision determinations of αs(MZ2), that based on the analysis of short‐distance‐sensitive lattice observables, and that based on an analysis of hadronic τ decay data, have, until recently, yielded results differing by ∼3σ. I review recent updates which bring the two determinations into excellent agreement, and discuss prospects for additional future improvements.
