Determination of \alpha_s from Event Shapes and Power Corrections

High Energy Physics - Phenomenology 2009-10-30 v1

Abstract

The size of non-perturbative corrections to event shape observables is predicted to fall like a power of the inverse centre of mass energy. These power corrections are investigated for different observables from e+e-annihilation and compared to the theoretical predictions. Using the latest DELPHI high energy data advantages of determining \alpha_s from these predictions are discussed and compared to conventional methods.
