The back-to-back region in e+e- energy-energy correlation

We consider the back-to-back region in the energy-energy correlation in e+e- collisions. We present the explicit expression of the O (αS2) logarithmically enhanced contributions up to next-to-next-to-leading logarithmic accuracy. We study the impact of the results in a detailed comparison with preci...
