Аннотация:
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 $(Y_{3})$. This parameter is one observable among the event shape variables. Both models are divided into the perturbative as well as the non-perturbative regions. The average value of the strong coupling constant is $\alpha_{s}=0.11887\pm 0.03537$ being consistent with world average. We will explain all these features in this paper.
