Measurement of event shapes and ${\alpha }_s$ in $e^{+}{e}^{-}$

Abstract

We report results on measurements of the strong coupling \as from event shape data at \Petra and \Lep. These include analyses of their distributions employing the recent NLLO calculations and analyses of their moments using NLO and power correction predictions.
