Abstract

We study the application of the Brodsky–Lepage–Mackenzie (BLM) scale-setting prescription to event-shape distributions in electron–positron collisions. The renormalization scale is set dynamically according to the BLM method. We study NLO predictions and we discuss extensions of the prescription to NNLO.
