Power Corrections at LEP

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

The size of non-perturbative corrections to event shape observables is predicted to fall like powers of the inverse centre of mass energy. These power corrections are investigated for different observables from e+ee^+e^--annihilation measured at LEP as well as previous experiments. The obtained corrections are compared to other approaches and theoretical predictions. Measurements of αs\alpha_s using power corrections are compared to conventional methods.
