We describe in this paper the quantum chromodynamics prediction to calculate the strong coupling constant by using event shape variables as well as momentum spectra. By fitting the dispersive model and employing our parameters on event shape distribu

We measure the coupling constant ( $$\alpha _{s}$$ ) as well as the non-perturbative parameter ( $$\alpha _{0}$$ ) in QCD theory by using the renormalization equation and also the dispersive model. Our analysis is based on employing the event shape o

This article is based on renormalization analysis by using the single dressed gluon (SDG) approximation. This model is used to measure the coupling constant in perturbative as well as in the nonperturbative part of the QCD theory. We employ the event

We describe the measurement of the coupling constant from both the dispersive and the shape function models. This parameter depends on the scale at which the QCD process occurs. We present distributions of the jet resolution parameter (Y3). This para

The average of the moments for event shapes in e + e− →hadrons within the context of next-to-leading order (NLO) perturbative QCD prediction in dispersive model is studied. Moments used in this article are $\langle {1-T}\rangle$ , $\langle \rho\r

We have analyzed the hadronization process in $$ {e}^{ + } {e}^{ - } $$ annihilation. We use Monte Carlo data simulated by PYTHIA program. We have compared our results with AMY real data. Similar analysis techniques have been employed in the two diff

We present the properties of the C-parameter as an event-shape variable. We calculate the coupling constants in the perturbative and also in the non-perturbative parts of the QCD theory, using the dispersive as well as the shape function models. By f

We measure the strong coupling constant at NNLO corrections. We do this analysis with moments of event shape variables: thrust, C parameter, heavy jet mass, wide and total jet broadening, by fitting the L3 and DELPHI data with NNLO model. Our real da
