Determination of αs(MZ) from energy-energy correlations in electron positron annihilation — •Andriii Verbytskyi1, Adam Kardos2, Stefan Kluth1, Gabor Somogyi2, and Zoltan Tulipant2 — 1Max-Planck-Institut für Physik, Föhringer Ring 6, 80805 München — 2MTA-DE Particle Physics Research Group, University of Debrecen, 4010 Debrecen, PO Box 105, Hungary
A determination of the strong coupling constant from data collected in e+e− collisions is presented. The measurements of energy-energy correlation from multiple experiments confronted with perturbative and resummed QCD predictions. The nonperturbative effects are studied and incorporated in the analysis via Monte Carlo models that include modern shower algorithms and higher order corrections to QCD matrix elements.
