Precise determination of the strong coupling from energy-energy correlation

Abstract

In this contribution we present a determination of the strong coupling from a fit of QCD predictions for energy-energy correlation measured in electron-positron collisions at various center-of-mass energies. Experimental data are compared to precise theoretical calculations incorporating NNLO QCD predictions combined with NNLL resummation in the back-to-back region. Hadronization corrections are assessed using modern shower Monte Carlo programs matched to NLO fixed-order computations. The final result obtained from a global fit is $\alpha_S(M_Z)=0.11750\pm0.0287(comb.)$.
