Precise determination of $\alpha_S$ ($M_Z$) from global fits of $e^+ e^−$ data to NNLO+NNLL predictions

We present a comparison of the computation of energy-energy correlations and Durham algorithm jet rates in $e^+e^−$ collisions at next-to-next-to-leading logarithmic accuracy matched with the next-to-next-to-leading order perturbative prediction to LEP, PEP, PETRA, SLC and TRISTAN data. With these p...

Descripción
Sumario:We present a comparison of the computation of energy-energy correlations and Durham algorithm jet rates in $e^+e^−$ collisions at next-to-next-to-leading logarithmic accuracy matched with the next-to-next-to-leading order perturbative prediction to LEP, PEP, PETRA, SLC and TRISTAN data. With these predictions we perform global extractions of the strong coupling constant taking into account non-perturbative effects modelled with modern Monte Carlo event generators that simulate NLO QCD corrections.
