Abstract
Me describe the measurement of the coupling constant from both the dispersive and the shape function model. This parameter depends on the scale at which QCD process occurs. we present the distributions of the jet resolution parameter (Y3). This parameter is the one observable among the event shape variables.Both models are divided into perturbative as well as the nonperturbative regions. the average value of strong coupling constant is 0.11887 being consistent with the world average. we will explain all these features in this paper.
