Energy-energy correlation in electron-positron annihilation at NNLL+NNLO accuracy

Abstract

We present the computation of energy-energy correlation in $e^{+}{e}^{-}$ collisions in the back-to-back region at next-to-next-to-leading logarithmic accuracy matched with the next-to-next-to-leading order perturbative prediction. We study the effect of the fixed higher order corrections in a comparison of our results to LEP and SLC data. The next-to-next-to-leading order correction has a sizable impact on the extracted value of ${\alpha }_{\mathrm{S}}(M_Z)$, hence its inclusion is mandatory for a precise measurement of the strong coupling using energy-energy correlation.
