Abstract

A summary of the latest alpha_s results at LEP1 and LEP2 from event-shape predictions at Order(alpha2_s) + NLLA is presented. Later these are compared to measurements obtained using the Experimentally Optimized Scale method. Finally the alpha_s measurement from the 4-jet rate is discussed.
