摘要

We give perturbative predictions for the distribution of the $C$ -Parameter event shape variable in $e^+e^-$ annihilation, including resummation of large logarithms in the two-jet (small- $C$ ) 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.
