Tests of analytical hadronisation models using event shape moments in e + e − annihilation
Predictions of analytical models for hadronisation, namely the dispersive model, the shape function and the single dressed gluon approximation, are compared with moments of hadronic event shape distributions measured in ee annihilation at centre-of-mass energies between 14 and 209GeV. In contrast to Monte Carlo models for hadronisation, analytical models require to adjust only two universal par...
متن کاملFROM HADRONIC EVENT SHAPE OBSERVABLES IN e+e− ANNIHILATION
We have applied so-called ‘optimised’ perturbation theory to resolve the renormalisation-scale (μ) ambiguity of exact O(α2 s) QCD calculations of event shape observables in e+e− → hadrons. We fitted the optimised predictions for 15 observables to hadronic Z0 decay data from the SLD experiment to determine αs(M 2 Z) . Comparing with results using the physical scale μ = MZ we found no reduction i...
متن کاملSuppressed power corrections for moments of event-shape variables in e+e− annihilation∗
Power corrections that fall as 1/Q, where Q is the center-of-mass energy, play a significant role in the phenomenology of the average values of event-shape variables like the thrust T . These power corrections can be analyzed in perturbative QCD using renormalon resummation in the single dressed gluon approximation. They originate in a particular part of phase-space where a soft gluon is emitte...
متن کاملMoments of event shapes in electron-positron annihilation at NNLO
This article gives the perturbative NNLO results for the moments of the most commonly used event shape variables associated to three-jet events in electron-positron annihilation: Thrust, heavy jet mass, wide jet broadening, total jet broadening, C parameter and the Durham three-to-two jet transition variable.
متن کاملNNLO moments of event shapes in e + e − annihilation
We compute the next-to-next-to-leading order (NNLO) QCD corrections to the first five moments of six event shape variables related to three-particle final states in electron-positron annihilation; the thrust, the heavy jet mass, the C-parameter, the wide and total jet broadenings and the three-to-two-jet transition parameter in the Durham algorithm Y3. The NNLO corrections to the first moment a...
