Description
In this talk we consider the back-to-back region of the
energy-energy correlation in $e^+e^-$ collisions and present the matching of
the next-to-next-to-leading logarithmic (NNLL) approximation with the recently
computed fixed next-to-next-to-leading order (NNLO) corrections. We perform the
matching in the log R scheme. We compare our results to precise LEP and SLC data,
and find that the inclusion of the NNLO corrections has a sizeable impact on the
extracted value of $\alpha_S(M_Z)$.
