Abstract
We give perturbative predictions for the distribution of the -Parameter event shape variable in annihilation, including resummation of large logarithms in the two-jet (small-) region, matched to next-to-leading order results. We also estimate the leading non-perturbative power correction and make a preliminary comparison with experimental data.
