Resummed $C$-Parameter Distribution in $e^{+}{e}^{-}$ Annihilation

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.
